okay gotcha, and I probably should install cobl and armamentium before MMM right?
CorePC is better at install order than me, but IIRC you should install COBL after MMM, as COBL will then install some special compatibility plugins.
OH and I can delete the living economy esp's from OOO and install yours right? figured I'd ask before I finalize installations. I keep forgetting things..
Yes

Just make sure to read LE's uninstall instructions:
Living Economy:As of version 2.15 disabling the mod via this method is not really needed to return merchant's gold to game default. But if you are updating from a version previous to 2.15 you should follow this method, at least only once.This mod changes the barter gold amount on EVERY NPC in the game. Even if you just disable the plugin, those changes will remain for any games that were saved with this plug-in active. To properly uninstall this mod open the customization menu by typing "startquest cflemenu" (no quotes) in the console and select "Disable Mod". You DON'T have to immediately stop playing. Everything should work as if the plugin was actually disabled. Once you actually disable the plugin there is a VERY SMALL possibility that any investments you made while using this mod will be forgotten (none after 3.0). Living Economy - Items:You should save the game outside any shop to ensure the prices are correct before uninstalling this mod. Keep in mind prices are similarly set permanently, so once you remove LE Items, the prices won’t change unless an external price changing plugin is added after LE Items removal.
So how do I add everything, just click add archive for each zipped file? but what about the bsa it doesn't show up when I load it.
You mean in the omod creation dialogue? Have you noticed the two radio buttons at the bottom? The bsa file is considered a data file, so it will show up only if you click on the "Data files" button, but it has been added anyway.
Edit: beaten by Corepc...
