Off the topic a little, but I've had a lot more success with google since I created a sitemap.xml file my site has been up less than 2 months and Googlebot is there at least once a week and sometime two. I also registered my sitemap.xml with google at:

You can setup a script to submit your sitemap every week or month or just when the content changes. Good luck!
