Well, I don't really know of any tutorials, but I can give you a few tips:
First off, there's no keg in 1v1 maps. So you don't have to worry about that. Now, shield belt is a very important item so you should TIME it - it spawns every 55 seconds, so if you take it or hear someone else take it you add +5 seconds on the clock and you know when it spawns next time, so you can either challenge for it (if you have 100 armor/suspect enemy is weak) or set up a trap (get a shock combo ready and wait in the boots alcove on Deck, for example, and combo the enemy if they mindlessly run for shield belt).
If you are out of control, your best bet is to try to stack up using vials and 100 armor and try to figure out the belt timing, challenging it next time you have a good enough stack. Either you will take the belt and establish control, or you will at least damage the enemy enough to where you can be a threat to them with no armor.
Best tip about this - don't mindlessly attack an opponent that's in control right off the spawn. It might seem like a good idea since you could quickly regain control (and indeed, sometimes you can if you get lucky) but it's usually better to die 2-3 times while trying to stack up and play defensively, instead of dying 10 times at which point you pretty much have no chance to win the match at all. The latter is what generally happens if you mindlessly attack while out of control. If you are only 2-3 frags behind, you can usually get them back in time unless you are playing Liandri (that map is extremely defensive, some games end up being 1-0. So you have to try to not die right off the bat, or you might never catch up again)
Weapons are pretty self explanatory and the only way to learn how to use them is by practice. Rockets and Flak are good for close range, tight corner fights. Flak is pretty good at swinging control in your favor as one primary hit with all shards nullifies shield, I believe.
However in open areas it depends on luck a lot whether you hit with it or not, weapons like minigun and pulse + good dodging are better in this situation. These two are also very useful for finishing off your opponent - if you flaked someone in the face and they are now at low health, it is more reliable to use a fast firing weapon like mini or pulse to finish them off, instead of risking missing several times with high damage, slow firing weapons like Flak and RL.
Sniper is misleadingly good in close range and sometimes it's better to stick with it even if someone closed in on you with a close range weapon instead of trying to switch weapons - if you have good aim, you can pop their head off easily; switching weapons could take a while if you just fired. This is one of the most important weapons to master.
Shock rifle is very important as well, combos do massive damage and primary can be used to fight off a sniper player (pushback throws off their aim). If someone closes in on you with flak or rockets, spam Shock alt (cores), as they block most projectiles and have pushback.
When you spawn, use Enforcer instead of Impact Hammer - it's pretty powerful if you have good aim and doesn't reveal your position like charging the IH does.
Bio Rifle and Ripper are mostly good for spam and defense only, but you can get lucky shots with them; use them only if you don't have other weapons. Bio primary is pretty much useless, use charged up secondaries and try to predict where your opponent is going (shoot at armor, weapons, boots). Minigun primary is only good for long range if you have good aim, otherwise use secondary. Pulse primary is useless, use only secondary. Sniper is best to use without zoom as it has a bug where it zooms in all the way even if you don't want to, and most maps are small enough to get by without it.
Dodging should be used to traverse the map faster but should be used sparingly when fighting. When facing opponents with Flak or Rockets, unless in very close quarters, try to evade them with just strafing, and dodge once in a while right before you think they will fire. Against Shock primary, Sniper, Enforcer - strafe is your best bet, it's fine to dodge sometimes to throw them off, but most of the time dodging makes you more predictable. Shock combos can be dodged with dodges if you already see one flying at you and can't walk out of its range, but if someone is trying to predict where you are going with cores, you can strafe back and forth to throw them off, and if they shoot a core in the middle of your strafing pattern, you can dodge out of the way. After you land a dodge, you are completely still for a moment, so that's why it is best to use strafe sometimes.
About maps - sorry, I can't really give much advice here. Just practice and you should get better. You need to know where the pickups are.
To change the perspective you are spectating from, open console (~) and type "behindview 0" or "behindview 1" without quotes.
To record demo, in console type "demorec name" and it will start a demo, saving it to your UnrealTournament/System folder. There's a good tool called Demo Manager, that can simplify the demoing process and get rid of some demo bugs, http://medor.no-ip.org/index.php?dir=To ... demo34.rar
Essential commands are for example disabling red screen for visibility (the flashes you get when you are damaged). Type "preferences" and hit enter in console, then make sure ScreenFlashes is set to False.
For network performance you can't do much, just play around with the "netspeed xxxx" command, where xxxx is a value up to 20000. Don't try anything below 6000 or you will probably get lag, it depends on your internet connection and the server but most people use either something around 10000 or 20000.
Input lag - just make sure SwapInterval is set to 0 in your ini/preferences under your renderer (I assume you already got one of the new ones like D3D9 or OGL, that should be in the performance tweaks tutorials) and Vsync isn't enabled in your drivers.
Finally play around with the setting FrameRateLimit in your ini/preferences - I use 1 below my monitor's refresh rate, you might find best results with something else - like your exact refresh, or 10 above that, etc. This affects how much screen tearing you get and should stop some lags on servers due to variable CPU clock.
Also if you are serious about competitive games like UT99 and Quake, you should get a 144hz LCD or a CRT if you haven't already. They can improve your aim.
For IRC channels these are some competitive UT99 ones, they aren't 1v1 only but if you ask around I'm sure you can find someone to play.

Anyways, hopefully this is helpful, if you have any more questions you can ask me, I'm not great at duel but I can try to help
