Documentation these days will never be as valuable as docs on a First Gen, However, It is still cool to keep them. I am not a big fan of lamination because you have changed originality to your docs. If you plan on displaying them in your garage, office etc..... acid free framing w/ UV glass is the ticket but it is costly. If you do not plan on displaying them, simply place them in a folder (preferably between 2 pieces of acid free paper) in a dark dry place and they will be fine.
