I used different fonts with sizes 14-16. Pictures I tried to keep between 2.5-3 inches tall and 1.8-2.5 inches wide. To save paper, I typed up all my words on a couple pages, then all the pictures, which I adjusted the sizes of so they'd fit. Then I cut everything out and glued it on.
As for the glue, I just used a regular Elmer's glue stick and computer paper. You don't want anything too heavy or sticky when working with computer paper. If you use cardstock or photo paper, I would recommend Photo glue.
If you want an example, you can look at the one I recently made: http://www.craftster.org/forum/index.php?topic=370171.0
