I second the advice to read The Bible Unearthed. It's a really excellent book that untangles OT history with archaeology and contemporary records.
It also points out that a lot of the 'conquests' and smiting in the bible between Israelites and the neighbouring tribes on their quest for the promised land didn't actually happen. Not that it excuses the bible writers for their fervid imagination writing such grotesque stuff.
The OT is mainly fighting, sex, rape, slavery and songs/poetry (which is actually good considering when it was written). The 10 commandments aren't the 10 people normally think of. I think there's several entangled stories of Moses getting them, and they're all different. Moses trots up and down Mt Sinai about six times, the poor old sod.
The NT is Jesus mainly, who I always thought was a pretty dull character and kind of a dick at certain points as well. Most of the good stuff in the NT is also in other philosophical writings and Buddhist texts predating it.
I do find the bible much more interesting now that I know it isn't literal truth though. Its all pretty fascinating Imo.
I'd also recommend podcasts by Robert M Price. He does the Human Bible and Bible Geek podcasts.
