Eh, if you're a beginner, FOMM is overcomplicated. Very few NV mods use FOMODs, and even then the majority don't need them. The extra features aren't exactly useful for beginners either, unless you want to pack al your mod files into BSAs or something.
Personally, I'd just suggest http://www.newvegasnexus.com/downloads/file.php?id=35003 - it's easy to use, even without reading the gigantic manual it comes with, and you might even know how to use it anyway! Just drop it in, play with your mod load order

I don't know about that. Even though I've used Wrye Bash since Oblivion (that's 4 years ago) I know how to install it and figure out any problems, but he mentioned being rusty with PC's so Wrye Flash, IMO, would be over-complicated. It can still be rather challenging for a new user.
FOMM is far easier to use. Install it, adjust your load order and play. But, then there's the game launcher. Pesky thing - (see next quote)
Then there's that pesky load order thing that the default launcher won't do anything for. You know, the one that can crash your game?
I do agree, but there is another way to sort your load order without FOMM. I didn't want to use FOMM until it was somewhere near being stable so just manually edited the text file located at [Drive]:\Documents and Settings\[User]\Local Settings\Application Data\FalloutNV\Plugins.txt
Sure, it says "please do not alter this file" but you can. Make a shortcut to it on the desktop and each time you add another mod to your Data folder (an esp) just write the esp name in that file. A manual load order. But, each time I'd use the launcher (before I had the batch file to bypass it) then check that file Fallout.esm would be halfway down the list so I'd have to re-order it all again.
I loathe the launcher and bypass it at every opportunity. I have a batch file to do just that as FOMM's "Launch Game" button uses it, too, unfortunately.
Thanks for that Nevada Skies link, my favourite FO3 weather mod is not here yet, so that looks like a suitable substitute for now
