Check the 00 Core. Of course if you don't have Frans do not check Frans esps etc. Check the 01 Resources if you are not going to use the BSA (see below). Check all mod compatibility plugins you need. RTM for the various options ! Some of those options may be available only if you have MMM - will check this - still this guide is not for FCO (sic) - MMM is required. RTM also for FCOM Core. Lastly and not leastly - READ the OP from the Current FCOM thread. You 've been warned.

Now, you HAVE to download the latest Unofficial FCOM Updates which contains :

FCOM_Convergence.esm
FCOM_Convergence.esp
FCOM_Knights.esp
FCOM_SpawnRatesReduced.esp
FCOM_SpawnRatesSlightlyReduced.esp
FCOM_SpawnRatesStronger.esp
FCOM_WarCry.esp  <-----Version 0.9.9MB3 do NOT use
UnofficialFCOMUpdate.txt

and use those in place of the respective FCOM ones. You do understand (after the reading you've done) that you should at least install the files in orange. For FCOM_WarCry.esp see the WC section of this guide. Now you can use the UFCOM_Convergence BSA instead of the FCOM meshes and texture resources - I like to unpack those BSAs so I can see the conflicts insid'em but you might as well not do this. I did it for you (edited - you still have to delete thumb.dbS and desktop.iniS). The real difference is the painebonylongs.dds (and the lowercase everywhere - may be useful for the Linux crowd). If you want to use the bsa itself, I repeat, do not use the resources from FCOM\01 Resources.
Download Entropic Order rebalance from the FCOM Site (direct link). Choose one esp.
Another esp I found in BoM's guide is FCOM Archery beta 1. See for yourselves.
Those are obsolete (again from BoM's guide) :

• Shivering OOO : see discussion here
  
• Mass AI by Corepc allows high-end machines to fight 10 - 50 enemies : use the tweak option of Bashed Patch
  

TheNiceOne's OMOD Installer - check the script.

DONE !
