EBlogTemplates.com has some wonderful How-To articles. Hoping to improve my google ranking, I changed the order of my post title tags. I also learned how to remove the Blogger Navbar (done at my own risk of igniting Blogger's fury).
Awhile back, I learned how to put a "favicon" on my blog and website. I used HTMLSource.com and Mircroangelo as resources. Doing a google search for Favicon will bring up more resources.
