I recently became vegetarian as well, I was just about to post a journal about it because I was curious about things nutrition wise. I know you don't get a lot of iron when you don't eat meat, so you need to make sure you get vitamins. Hm. I'll post that journal and see what I get.
I can give you tips for being a veggie if you wantt =] I was one not too long ago. I went back because my parents were all gr.. >_< I'll be going back this summer though :]
