Screwing Question

I am in the home stretch!
I just recieved my molding from Grant and want to put together a shopping list.
I got the regular RV molding and what kind of screws and length did everyone use? (3/4" walls)
For the galley molding did you use the same? And does the lip of the molding go toward the galley or toward the outside?
T molding same question on what kind of screws.
Also a diamond plate question...would you put along the side of the molding or underneath?
Thanks in advance!
