Welcome to the board crazybull. If you understand how your 5.56 AR functions, then I think you'll be ok on the 308 version. Same theory, just some beefier parts. Don't really have anysuggestions on books or vids. But, you can usually find exploded diagrams on manufactures websites. That would at least give you listings of all the parts you'll need. With tools....a good bench vise, set of vise blocks, hammer, punches and torque wrench will get you going. Hell, the sky's the limit on tools that can be used.
