haha, i didn't actually search. there's a firefox plugin called
rank checker that allows you to type in a url and a keyword and see where you're listed on Google, Yahoo & MSN.
as for your PR, it's based entirely on back links. the more people you have linking to you, the higher your pagerank will be. it always helps to have high PR sites linking to you as well. basically, every site that links to yours is kinda like a vote in your favor. on the other hand, if you simply share links (i.e, a site links to you in exchange for you linking to them), it doesn't really help you, which is why i would try to stay away from having 50 "affiliates" linked from your page, unless they are high ranking websites.
there are discrepancies around how often Google's PR robot is sent out. sometimes it's every 3 months, sometimes every 4 months sometimes 5 or 6. it's pretty random. the last time PR was updated with 3 months ago, and it's estimated to run through again in a little over a week. all you can do is push to get high quality links in to your website.
you have 116 back links right now, all from PR 0 sites, which doesn't help very much. although, because you have so many links going to you, you'll probably jump up to a 2 or 3 once the robot updates. if you're affiliated with cB, it should help out a little, because cB has a PR 5.
how long has your site been opened?
