Just play and spectate good players.

Halo invented FPS.
Spectating will show you where to rush to once you spawn, but try playing against as many bots as you can at once. They won't act like players obviously but it's nice target practice. Once you can take out the bots (On the hardest difficulty, fighting against the most you can by yourself. Think it's 5 when you're solo.) you can then try your luck against other players. But just remember this game has been out for a while and there are people who will just rock you on every map even if you have the jump on them with a better weapon.
