SEO doesn't necessarily have anything to do with promoting a blog. I have PMed you a link for info on SEO.
If you want to promote your blog I would recommend:
Produce good content, preferably covering new ground - not the same old waffle
Comment on blogs all over the Internet (quality counts), particularly on similar blogs
Sign up to social networks (my advice would be StubmleUpon) integrate yourself into certain communites, use social media to promote others content and in turn you will make friends who will promote you
If your content truly has value, find similar content, see where their links come from and try and get links from the same sites.
I would not waste your time commenting on "A-list blogger's" blogs. Find other newer blogs and popular blogs be average joes. Look for blogs where the owner is engaged in discussion with commentors.
