Elite premium members I highly recommend you check out the Elite TV section. It has some really good overviews of all of the maps and primary weapons in the game. This content is done by IW so you get a clear idea of map play from the designers. They also label sections of each map which are good call out points for in game comm's.
They also have a Friday Night Fights which will show teams competing against each other. The first shows Army v Navy in Dom.
Good Stuff!!
