Hi bakeman2004,
that's a hell of a question and a lot of work to answer in a proper way. Fortunately Matt Woodward got into gear and wrote a pretty good guide on the matter.
Check it out:
Guide to capturing, cleaning, and compressing video:
Once you got your analog stuff digitized to hd, you might want to read
my post on how to grap and cap from digital devices.
Some links to A/D video converter manufacturers:
(just to give you an idea on what's out there)
Pinnacle Systems: offers some pretty good and reasonably priced solutions to get your tapes onto harddisc.
Canopus: does just the same, although their equipment tends to be more useful for the video professional.
That might help you out.
