Ok, a few general things about blogs and SEO:
1. Most important, for g**gle are incoming links to your site which contain your keywords as anchor text, so trade links, trade links, trade links. Don't do too many direct recip trades, perfer A->B->C triangle trades. This is because all big search engines know that link trades are a popular seo tactic and de-value a link if the spider spots a recip.
2. Forget PR, it's overrated alot. It's nice to trade with a PR5+ site, but if this site has 200+ outgoing links, you profit less from it than if you link is on a PR3 site with just 5 outgoing links.
3. Get plugins that optimize you linking structure, like

4. Make permalinks SE friendly:

5. Post text with a picture/gallery/gallery link, the more the better. Blogs are great for search engines, but spiders need some food and just a description and a pic aren't enough.
6. If you want first hand information about g**gle, check

Hope that helps a bit
