Marty:
As the previous poster mentioned, search the forums, most of your questions will be answered. But that requires some work on your side.
Regarding lamination, the reason for this is two fold:
1) to protect the image from physical damage if the print will not be framed behind glass.
2) to seal the microporous surface of the print from airborne contaminates which can attack the pigments of the inkjet ink and cause it to prematurely fade.
If the prints will be framed under glass, there is no reason to laminate the print. Ordinary Window glass filters close to 90% of UV from sunlight. In most indoor display conditions using incandescent lighting, UV is not a consideration. Under florescent lights, there is a significant amount of UV transmitted, so framing under glass would be recommended. The pigmented inks from Epson, Canon & HP are resistant to UV fade, much more so, than dye inks of years earlier. The addition of a UV laminate would probably not add significantly to the fade resistance of the print.
