need input on parts for a 904 rebuild!!!

OK i have a 74 dart sport with a 91 360 in it. its pretty much a stock 360 it is a factory roller cam motor with some bolt ons. tti headers, holly street dominater intake n a edelbrock carb. so not much in hp department. I just did a disc brake explorer rear swap in it. turned out very nice however i did have to swap gears i started with 3.73s n was way to much for interstate cruising. i came across some 3.30s n they worked awsome. the car has a a904 trans. recently it began shifting spuratic i ended up putting a trans go tf2 shift kit in it n am pretty happy with it. it did appear to take care a the problem. i have rebuilt several c4 ford transmissions n they turned out really well so i am going to do my 904 it was alot of clutch material in the pan n front band has little to no adj. left nor any frition material n rear band isnt much better so while it hasnt self distructed i want to freshin it up. i ordered a performance automatic kit through summit here is my question what if anything should i upgrade look out for etc while i am in this trans any helpfull tips etc i know to soak bands n clutches in fluid to prevent chatter n that vasaliene is awsome for holding thrust washers etc during assembly just wondering the do n donts n if its any must do upgrades for durability
