Is there a fallout new vegas mod that contains alot of other big mods that are all put together into one esp/esm?

Yes, NVEC is what you're looking for. http://www.nexusmods.com/newvegas/mods/44204/?
It's a bit outdated, but in terms of convenience it's hard to beat.

@rower97: That's a really good option for a large pack, i can't really think of any other large, all encompassing packs.

Really, i think the best bet for anyone adding a bunch of content to their games would be to simply go through the top rated mods on the Nexus and getting a lot of the stuff that jumps out at you. That would really be my personal suggestion. It's how I've always done it. Armor and weapon mods are very easily installed through any of the mod managers and don't conflict all too much.

For some of the more game changing mods like Project Nevada, you'll have to install those per the instructions given by the author. It's best to not deviate from their instructions if you want smooth installations.

unfortunately, there really aren't too many "all-in-one" mod packs out there for us. It becomes a game of picking and choosing what we want and taking the time to install stuff. I would suggest looking for some of the big overhauls to the factions that are available. The Caesar's Legion overhaul and NCR overhaul that Dragbody made are really good options and change a lot of armors that you see all the time. if you want weapons, i would say go for the Millennia weapon pack and EVE. All of those are really game changing and add in a ton of awesome stuff to your game.

I hope you end up with a fantastic load order of cool mods

There's New Vegas Enhanced Content, like rower97 said, it is outaded but for new modders it's really a breeze to install. There's also mods that merge other mods to reduce load order. Just search for "Merge" on the nexus and a few suggestion should pop up.

Very good point, that didn't cross my mind for some strange reason. Also a fantastic option if you like tons of gun variety

That weapon pack is perfect as standalone, so basically you don't need other weapon packs. But of course I have some more, you can't ever have enough weapons.

I would not imagine myself using any combined mods rolled into one huge pack though. I enjoy searching new different mods and modding my game individually.

NVEC is pretty damn broken at this point and I don't see it ever being fixed. It's got so many outdated and conflicting mods at this point that you're better off using individual mods :/
