Obviously get the someguy series quests. Bounty hunter quests I mean. Called New Vegas bounties IIRC, there's 1, 2 , & 3, and a few other side ones. One of the best imo is a side one called new vegas contract killer, which has you choose the "bad choice" and expands on it. Webm related.
There's also tales of new reno. Not everything is voice acted but its pretty good.
There's also an anatomy of disaster, which similarly is not fully voice acted but a good, pretty long quest.
Also, check out Jokerine on the Fallout New Vegas nexus, shes made a bunch of stuff, including data packs, dance animations and quests, all of which are also voice acted IIRC. I'm actually a pretty big fan of her christmas mod for vegas.
There's EVE, which expands on Energy weapons, and its effects. Also look for GunCaliberX, which REALLY FUCKING EXPANDS on bullets, types of bullets, and actually showing the casings of your rounds on the ground for every shot you fire, so after a massive battle you can look down and see your bullet casings fucking everywhere.
There's first person perspective which lets you see your body in first person when you look down.
I'm tired of writing mods that come to mind though. There used to be a wiki for a bunch of good mods that I and other anons used to post but I have no fucking clue where I saved the link anymore.

Dust. It does add in new crazy people and presets for you though.
