Professor,
It's a pretty common modification and although it's come up quite a bit on this and many other forums, it's a new experience for you so ask away! That's why these forums exist..so that those of us that have done it "a hundred times before" can help those who are doing it for the first time!
I'll tell you this, it's a fun and rewarding project that will make your old ride more reliable. I HIGHLY recommend doing the Delco alternator conversion. A good place to get started is http://www.fifthaveinternetgarage.com/ Randy Rundle is the owner and he's a heck of a nice guy. He can tell you what you'll need, and what you wont! He also has all of the parts in stock to make your conversion quick and easy. Between what he can tell you and what you'll learn here, you'll be an expert in no time!
Personally, I've converted 3 50's era Fords (including my 55 Ranch Wagon) and 2 50's GM products to 12 volt systems and have always had good results.
Good Luck.
