Hi there. I'm trying to figure out a rough theoretical outline of which mods it is relatively safe to use together, and the order in which I should install them. I want to be conservative with this, ie, I'd rather simply delete a mod that won't play nicely with others, than bang my head against trying to figure out weird load order stuff (though I do have the tools to do some of that).

Here's what I am thinking of:

A note easily missed

Auto aim fix - headshot deluxe edition

Better game performance

Blackened - Blackened FWE - MMM

CALIBR

Chems and Meds re-texture pack

Combat Enhanced Tactics

DCInteriors Project

Dogmeat Leather Armor

Enhanced Blood Textures

Enhanced Weather - Rain and Snow

Error Corrections - Reduce CTD

EVE - Energy Visuals Enhanced

eXcalibr Ammo eXpansion Pack

Fallout 3 Re-Animated

Fallout Street Lights

Fellout

FOOK2

FWE

In the Shadows of the Swamp

MMM

More 2 Megaton

More Map Markers

New Vegas Items and Weapons

Point Lookout Reborn

Realistic Death Physics

RI - Primary Needs

Rivet City Merchants

Scribe Yearling takes all Pre-War Books

Unique items - unique look

Updated unofficial fallout 3 patch

Weapon mod Kits

Does anyone have any suggestions of install order or which to strike? Or what other things I should add that help gameplay in LARGE ways?

Well you have a complex set of mods with Fook, FWE, Eve, Weapon mod kits, MMM. I think you might be missing a compatibility patch for WMK and FWE. Also you might have some issues with EVE and WMK as well.

I believe you do not need the autoaim fix since I FWE has that included.

Which mod manager are you using and it is recommended to use Boss or Loot to sort the mods. I still find that Boss is best to use unless you are using a lot of newer mods.

Planning on using Nexus Mod Manager and Boss GUI. Yea, there might be SOME compatibility patch somewhere.... I'm thinking of dropping EVE, I think it might not be compatible with some of those...

But it isnt JUST the mod order... it's the order of installation that appears to matter.

No it doesn't. It's only the order that is loaded into the game that matters, not how they're installed. And I'm not sure how well Enhanced Weather and Fellout will play together. They're likely to overlap as they're both making changes to the weather systems in the game. There's bound to be conflicts between them.
