effla

Hi all (hoping this is the right place to post it),
i’m an "old" gamer who played several times the original BG games.
I’ve also played enthusiastically, several years ago, BGT-WeiDU, i was always too much eager about the number of mods I wanted to play in my installation, this greediness of mine unfortunately caused bad playing experience and didn’t allowed me to finish Trilogy without blocking issues, stuttering, extreme slowness, etc.
After 7 years discovering the EEs modding possibility made my heart warm again and, obviously, full of memories, so I decided, for the sake of old times, to buy them all (also Icewind Dale and the masterpiece Planescape: Torment) to try another time the Trilogy playthrough.
So now i wish to start a new game and go through all the three BGs trying to do only simple things:

- Import my old character from my early 2000s games

So I'm writing here, asking for your help, hoping to understand If I am missing something important about my goal and the mods chosen.
Are there some tips I should know or am I missing out mods I should install that improve stability or are some must have (although I don’t want too many fearing it may “ruin” the game)?
Or in general is there something I should know or do to improve stability of the trilogy game?
Thanks for your help!
