While I don't use Lamination Pro that much I just did a quick 1st gen board to make chevrons.
The information is pretty much there in the print screen, except material needed. The Print screen gives the measurement of each strip (if you totaled them it would give you the board width). It does give instruction on how to cut the first gen and the width of the repeating unit.
When I have used LP, I just made a note of how much material I needed in the laminated board.
