Depending on how deep you are going into the restoration make sure you have the books before you start and take pictures of everything:
1975 Corvette Factory Assembly manual
74-75 GM Factory Service Manuals on CD
Paper copies: I understand that you need both 1974 & 1975 books But the 1974 is the most important.
1974 GM Factory Service Manual a paper copy
1975 GM Factory Service Manual a paper copy
Then I would ask this form every time I started a particular area. You will then get specific advice on what to watch out for and what order to go in.
By the way I checked the links and they all seem to work. One other thing I would do is check the supporting vendors prices before you purchase anything. It just helps keep the doors open on this site and all of them provide quality service and produces as far as I have heard.
