Answers:    no primer needed. use a mud wound to put a skim coat float of dry wall mudd on the bad places. tolerate dry and lightly sand smooth....no primer needed on peel spots or drywall. just prep and texture.

where on earth wall board is suseptble to moisture, by code, "green board" is used. don't sweat mold if it is not in a tub shower crate. just prep your drywall beside mud and sand smooth, then texture.

after texture you can stamp with kilz or of late paint. i would put a coat of primer on freshly textured wall then two coats of paint.

contained by this case i would use the grease, since you already have it. the grease is better but both are good. prime AFTER you texture and tag on some mildewcide to the paint so it doesn't come back. wear latex gloves when handling mildewcide, it is precarious stuff 'till it dries!
