Here is an excellent resource from www.bible.org. Bible.org has produced a translation called The NET Bible (and here) which uniquely includes the translator notes. They have also developed a web-based bible study tool called The NeXt Bible Learning Environment …check it out.
In addition, the following link is to 258 Theology Questions Answered from bible.org’s Theology Program for lay people. Each subject is usually a pithy video about the subject matter presented in a classroom setting. It only cost you $500…no, just kidding… it’s free! There are questions that give answers to the essentials to Christianity and also to some that are a little more controversial but makes note of that next to the link.
