I am the resident SnD expert (well, even moreso than other aspects of CoD).

You will definitely a want a silenced primary weapon. Depending on your playstyle, mobility may be extremely important or fairly minor. Also, Ninja Pro is the only third perk you should ever use. Your secondary weapon should cover your primaries weaknesses. If you have a sniper, take a machine pistol. If you have something else, take a Silenced Striker (unbelievably effective weapon). Your Perk 1 should be Marathon, Bling, or One Man Army. No exceptions. Marathon for mobile classes, Bling if you are actually going to use two good attachments (although I don't think that many attachments are worth your Perk 1), and One Man Army for two claymores and two C4. For Perk 2 you should use Lightweight with Marathon and a silenced UMP for extreme mobility, Stopping Power on classes where mobility isn't as important, and Cold-Blooded variants of those classes (keep track of enemy killstreaks via the scoreboard; if an enemy has a high K/D ratio, it's time to whip out the CB classes). Some good weapons are

TAR-21

SCAR-H

ACR

WA2000

UMP

P90

And IMO that's about it. Maybe the AUG HBAR, but that is a very sluggish way to play.
