Sorry for the late reply, I just found this post, but if you are still looking for some SEO Tips, here are a couple of great online tools that I use for a few of my sites
These do not have to do with links back to you, but the first two are great tools for bosting your rank up a bit
Website grader, has a neat feature that lets you compare your site to the competition to see where they are doing better or worse.

And here is a great tool to test those link relationships. You really don't want to link back to a link farm. I accidentally did with my design studio site & I droped from page 1 in google to page 6 overnight.

Not sure how much this really helps, but as long as you keep an XML sitemap currant - I figure it can't hurt:
