for those of you on broadband, type in the console (~ key)
/rate 25000
should help a lot with you lag problems
for some reason even if you set it in the GUI, it doesn't go to 25000

As for identifying teammates, it really easy:
1. Teammates aren't shooting at you
2. Teammates usually aren't coming at you (if you see 3 dots moving toward you, you can be sure they are badguys)
3. When you put you mouse over a teammate, their health will appear.
4. The Axis look slightly different then the allies. The Axis look wider at the bottom because they have a coat, while the allies look thiner because they have no coat.
5. Axis are black, allies a yellow,green puke color
