A little help with ordering

I *loath* asking for help, especially with BG2 modding, which I used to know fairly well. At least back before BG2:EE. And that's alright, never hurts to learn something new. So I could really appreciate some help

So here's my request for help. I can't find any clear cut method I understand to install a handful of mods I'm gonna list here. Effectively, I'm asking for help with order and instructions to make sure they all cooperate.

Ascension
SCS
aTweaks
Anthology Tweaks
Spell Revisions
Item Upgrade

What's really got me confused is SCS and Ascension. I don't know what order or what special directions I need. I also know SR and IU are either 'in progress' or not fully compat, but I know they used to work before the updates I have been MIA from.

Edit: Simple clarification fix
