Okay. More tips. The knife is much less effective than it is in MW2. Only knife someone when you are behind them, as otherwise you will get wasted, and not in the good way. Try to avoid relying on it for sneak attacks, anyway, as the hit detection for it (at least, on the PS3) is balls-awful. If the knife stab misses the first time, don't bother trying again, just shoot them.
In conquest, avoid the UAV at all costs. The minute someone sees the helicopter, they will run to the position for an easy kill.
Here's a good rushing class. Assault with the 870 Combat or the NS2000 (avoid the SPAS-12, it's the worst of the shotguns, IMO). Perks should be Lightweight Kit (+ sprint speed) and Body Armor (+ health). Pistol should either be the MP-443 or the WWII pistol. And there you have it: the perfect class for the smaller conquest maps.
Don't bother using sights or Magnum Ammo with the M60. You will need the extra ammo perk, and the ironsights are perfectly fine. Magnum Ammo only saves you about two bullets to kill, so it's not that worth it.
Don't use the SV98. It's got worse stats than the M24 in damage and accuracy, in exchange for a 10-shot clip. Using it with a 4x Scope or Red Dot sight is fine, but the GOL is still better.
That's all I've got for now.
EDIT: Oh yeah. When you hear a motion sensor go off, check you minimap immediately. If it's a friendly one, it can tell you where an enemy is. If there is no such marking on the map, either get the fuck out of there or stand still. If you don't move, you won't show up on enemy motion mines, which at least evens the playing field.
