Easy Off Oven Cleaner is also a good paint stripper.  Not as safe as the other things mentioned but it works faster - your kit comes clean within a couple of hours.  For fresh paint like you've got, it's almost instant.

As for the seams, I picked up red spot glazing putty at an auto parts store.  I like it better than Bondo because you don't have to mix it to get it to "work" - just use it straight from the tube.  It's essentially the same stuff as Squadron putties.  I thin it sometimes with Testors Liquid Cement to get it into smaller seams.
