The Prima strategy guide has all the maps you'll need and also pleanty of nifty tables that have stats for experience, classes, spells, items, and such. I don't know if it's still selling at full price, but if it's on sale I'd pick it up. The game itself is pretty straight-forward. There are some hidden areas in each location and the occaisonal puzzle. If you get stuck on a quest you can always check out GameFaqs.com
As for camera angles, you might be able to download a mod that allows you to move the camera more. I found the game to be suitable as is, so I never bothered with anything like that though. You should be able to find some more info on mods over at PlanetDungeonSiege:
