Welcome to the board.
I am in the wash before cutting group. I avoid precuts because I think if other fabrics should be washed / shrunk before sewing them, so should precuts.
I usually use steam when pressing . I don' t usually use sizing or starch.
Eventually, you will do what is "right" for you.
There are about a gazillion other threads on the topic. So far, it's still some do, some don' t.
