trans etc...change-out questions

[FULLPWR]

I recently pulled the trans to replace the broken t/o bearing, and will be putting it all back together this weekend. I been going over as many of clutch changeouts threads and have gotten so much info, some of which i wish i had read first, but some questions i just cant find the answers to.
it takes a while to read the threads but you cant just stop and go to another cuz there is so much dam good info.
I just have a few questions i need help with..

I did not mark the location of the pressure plate as it was bolted to the f/w when i removed it....what should i do putting it back?
(oh I did not remove the DM it is still mounted)

red loctite on p/p, trans, housing, pivot ball,ect...right?

i have the exact amount of bmw oil from bill, should i drain the trans while its out and fill it when its in, to keep from losing oil when working the trans in? just to make sure i get the exact amount in as instructed

what is the best grease you guys recommend for the shaft & t/o i.d. ?
