Oooh, thank you for posting! What a delightfully comprehensive list!

I also really liked Orson Scott Card's Science Fiction Writing book (yeah, I know people hate him - just check it out from the library), and On Writing by Steven King (which admittedly isn't really a "how to" book so much as autobiography - but it's fun, and gives a really interesting view as to the creative process from a very successful author). I do love Strunk and White, but the Chicago Manual of Style is also good. ;)
