Online Resources for Learning:
Chinese Grammar Wiki A terrific resource for learning Chinese, especially with grammar. Search or use the categories to browse by difficulty level.
About.com's Mandarin Lessons I found this site really helpful for more explanations on a grammar topic I didn't quite understand. There are also some great articles on pronunciation, tones, and character tips.
