It depends on your playstyle. If you're after firepower you want FMJ. If you're a camping bastard try the grenade launcher, and if you're sneaky you want a silencer. Try using the bling perk to experiment with combinations.

No, there will never be COD MW2 for PS2. Only for PS3, XBOX360 and a PC.
I like to treat this gun as an SMG. So, I would put it in my knifer class. But for overall uses, I would use these perks: Scavenger- It's ammo loadout is puny and burns through fast due to its high fire rate. Stopping Power- Damage is what the F2000 lacks the most. So do the best you can to increase it. Steady Aim- If you're going to hip-fire, it's mediocre accuracy is not going to help you at all.

No.
Reach Prestige 1 and Level 69.
mw2 is awesome but black ops is kinda crap
