according to your txt file, you've got 161 active esm/esp's, so you may be running into the magical mystical mod limit. you know, the one where FNV starts getting real screwy/crashy when there are too many mods loaded. the actual number seems to vary from computer to computer, but most people seem to agree that it's somewhere around 150-160. once you hit the magic number for your computer, just about any mod you add will make your game crash or act weird. you should really look into merging/consolidating some of your mods.
one bit of help i can offer is for [url=http://newvegas.nexusmods.com/mods/35979//?]Dree's More Perks[/url]. there is a merged version available on the [url=http://newvegas.nexusmods.com/mods/44204/?tab=2&navtag=%2Fajax%2Fmodfiles%2F%3Fid%3D44204&pUp=1]NVEC - New Vegas Enhanced Content[/url] dl page. their merger replaces 12 of the More Perks/More Traits esm's/esp's with one single More Perks.esm
also, [url=http://newvegas.nexusmods.com/mods/39651/?tab=2&navtag=%2Fajax%2Fmodfiles%2F%3Fid%3D39651&pUp=1]Weapon Mods Expanded - WMX[/url] now has a merged WMXUE (Ultimate Edition) version, which will reduce your load order some more
