Blogging Layout Help

In trying to vamp up my blog in a cheap, DIY sort of way, I came across some websites that were really helpful, so I want to share them with anyone else looking to do their own layouts/html/graphics/etc.  I still have tons to learn, but I feel as though my geek points exploded from their -1000 standing a week ago.

For graphics help:

Picnik.com  - super easy to use, and also does collages.
Paint.net  - sort of like a free photoshop.  I'm still learning this one.

A few layout sites:

Leelou Blogs
The Cutest Blog on the Block
Shabby Blogs

HTML help:

Blog Secrets
The Girl Creative

I'd love to make this a running list.  Are there any great spots and helpful tutorials that I've missed?
