I test for bleeders before using my fabrics and only wash if needed. I starch my fabrics and my back but not too heavily. I do starch the top side of my backing rather than the wrong side that would be against the batting. I have not had a problem with it sticking to my front and back. I have only once had a problem with one quilt not sticking well. I don't know if it was the fabric or a faulty batt but it stuck well enough to FMQ. I did have to iron it twice though.
