Greg,
I'm big into scrapbooking and decided a couple summers ago, after a trip running down the East Coast from VA to FL lighthousing, to create a lighthousing scrapbook. I do full albums, so it's a bit bigger than what you suggested, but what I added to each light was a block of info on every light ( Year built, tower height, Lens size (original if it'd been replaced), # of steps in the tower and approx. visbility of lens) I then added any photo's, postcards, stamps, handouts etc... to the pages. While it's not ornate in the realm of scrapbooking, it is by far my favorite album that I've created in the last 12 years. I would highly recommend putting something together, and leave room for additions! I'm happy to say I've had to make several addendums to my album, or updates to the lights' status etc... The other thing I added in the front was a list of all the lights I've seen in person, with a spot for marking if I've been able to climb it. I know for many of you that would be nearly impossible, but for this newbie it's neat to track them and put my little star next to them once climbed! Good luck in your endeavor!! If i can help in any way, holler!
