Writing reading for the reading non-writer?

I'm engaged in a little self-study program right now, reading books on writing in the hope that the collective wisdom and frustrations of "real" writers will somehow shake off onto me before November and I'll be able to get through this year's novel without tears, angst, and ennui. I've no illusions that I'm going to be the next Great American Novelist, but I'd like my writing to be at least of a quality where I'm not far too embarrassed and ashamed to show it to anyone. Any recommendations? Thus far I've read and enjoyed:

• The Moon and I by Betsy Byars
• Writing Down the Bones by Natalie Goldberg
• Bird by Bird by Anne Lamott
• Sometimes the Magic Works by Terry Brooks

In the "read and found OK pile" we have:

• Why I Write Will Blythe (ed.)
• Zen in the Art of Writing by Ray Bradbury

And because I really need to:

• The Elements of Style, Third Edition by William Strunk Jr. and E. B. White

I'm still slogging through Elements, as penance for being a chronic hyphenator and parenthesizer and all-around style butcher. Plus, I've found discussions of nominative form to be great for insomnia.

If you're familiar with the first three titles, you can probably see a theme evolving: books by writers who spend time procrastinating or advocating the "just write it down" school of thought. Bradbury's book had some interesting thoughts on writing using free-association word lists as a basis. I'm gathering up advice magpie-fashion, so any suggestions you can send my way are welcome.
