*The first thing I recommend is to apply the ifpsclamp=60 fix into you INI (easily Googled).
The game has major, major stutter otherwise and none of the stutter fixes help much. You MUST have your quality settings so you don't fall below the refresh rate (i.e. 60FPS) or else there are major synch issues.
(The same applies to Fallout 3, however you should also apply the 2-core fix for F3 if you have more than two cores.)
MODS:
I think you'd be better off just sticking with NEXUSMODS which I assume you use.
Go to Categories, then perhaps "quests and adventures" in your case and filter by best rated: http://www.nexusmods.com/newvegas/mods/categories/?
