New "mostly vanilla" install from scratch

I just bought TAK & IP from GOG and have a few questions on the various patches and updates I see. What should I install for my initial "mostly vanilla" load?

A) NoCD patches (don't need this cuz GOG takes care of that, right?)
B) 3.0bb patch containing the Darian Crusades (but GOG has the 4.0 patch, I think)
C) 4.1bb patch, do I need 3.0bb if I use this?
D) the new pathfinding patch (dated July 10, 2016 but some say this doesn't work)
E) the CUT balance hpi file (but it sounds like this may be included in 4.1bb)
F) the Ultimate TAK Pack v1.0. (is this still a recommended patch?)
G) what else did I forget?

Which of these do you consider "necessary" to have an up-to-date, bug-free (mostly, anyway), minimally frustrating build? I won't be doing much online, but I will be playing with various mods, races, and AIs with TAKSwitcher.

I would have thought a question like this would have been sticky'd somewhere, but I couldn't find these answers all in one spot and the answers I DID find where from various sources and dates, so I can't tell which are still valid. Thanks for any guidance you can offer.

Most vanilla: TA:K + 4.1bb update + GameRanger for playing online.

You could get it here if you hadn't bought: http://alltakdownloads.6te.net/Downloads/Setups.php

Mods, races, anything (TA:K Switcher): http://alltakdownloads.6te.net/Downloads/All%20TAK%20Downloads.php

Some you need TA:K Switcher, others you don't. In my channel you can check out some tutorials: https://www.youtube.com/user/AllTAKDownloads/videos

Here is how to install a mod without TA:K Switcher: https://www.youtube.com/watch?v=HsKSyAfb-xs

A) Yes, also TA:K Switcher comes with nocd patch.
B) Use 4.1bb, or 4.0 from GOG. One difference is that you can't use Creon on multiplayer (GameRanger) against 4.1bb players.
C) No. Always use 4.1bb.
D) Don't know, talk with Vaerun he must know better than me and help you.
E) CUT Balance is included in TA:K Switcher I guess.
F) Don't get that if you already have the game.

Hope this helps.
