Just a few links from a quick google search on 'scrapbooking'. Some of the most important things to look for are:
acid free- many papers have this in it and this will eat the paper on your pics, kill the picture
lignin free- lignin in short, is the stuff that makes the paper discolor
buffered- a buffered paper has a low enough pH that it will act as a 'buffer' between your photos and any higher acid content you may place on the page, it will help minimize the acid from migrating to your photo
Stay away from any plastics that have PVC (poly vinyl chloride)... this produces a gas that will also negatively affect your photos and items you are trying to preserve.
Remember it's okay to 'crop' or cut your photos (so long as you have the negative, just incase you'd want further copies in the future).
I originally got hooked up with Creative Memories
http://creativememories.com/ back in 1992 before scrapbooking became a massively popular thing.
I belong to the 'school' of 'Less is More' so I use some of the additives, i.e. stickers and diecuts, but not so they over run the photos.
Journal, Journal, Journal... about your photos. And do so in your own handwriting as much as possible it will preserve an additional piece of who you are for the future generations who see the albums.
