Halo 2 help

[DuFresne]

As a long-time PS2 owner, I never really got to play any halo very much. Well, now I'm in college living in a suite, and one of my suitemates put his Xbox and big ol' TV in the living room. I'm glad to say that I don't totally suck balls at halo multiplayer (I'm mediocre), but I'd like to get better, and I know Andrew (the Xbox owner) isn't gonna give me any pointers. Anybody got any little tricks or techniques that'll help me out?

One problem I know I'm having is getting used to the Xbox controller. The sticks have more resistance than a PS2 controller, and it seems like by the time I've applied enough force to move the stick at all, it loses all that initial resistance and flies straight to the edge, leaving little ability for articulation. Any suggestions?
