The rules:
1) You can bring anything you want to the past, but you can't leave anything behind. So you can't bring back the polio vaccine and start treating people. It wouldn't work.
2) You can't take anything forward with you, either, except for information. So you could, say, travel back with a copy of a book and a pen, and have the book signed with that pen. Or you could bring a camera and take pictures. But all things must be somehow made from materials you carried with you.
3) You can't get sick in the past, but you could be eaten by a T-Rex. No one native to the time periods you're visiting will notice anything odd about you.
For my personal use, I would pack a bunch of digital cameras, Flip video recorders, and a gene sequencer, and hop back to Messina in 1347. I would then document the Black Death in ten year jumps, with lots of photographs and recordings of people trying to breathe as they fully expressed the virus. And then, when I got back to the present, I would drive the CDC insane...but I would finally know for sure.
For the good of all mankind, I would hop back to the pre-tape losses BBC archives with a tape-to-DVD portable recording rig (and a technician), and get copies of all the missing Doctor Who serials. Upon returning to the present day, I would probably also get knighted.
So what's your personal use? And what's your use for the good of all mankind?

This would take some Very Careful Navigating, but...I'd jump back to 1845 in order to track a very particular wagon train that got lost in eastern Oregon and -- while lost -- came across a gold deposit now known as the lost Blue Bucket mine. With a series of very short and very precise hops (and the judicious application of videography and matching of maps with modern GPS data), it ought to be possible for a timejumper to determine exactly where along the train's path they found gold, thereby enabling present-day me to capitalize on the knowledge.
For all mankind:
Through some combination of stealth, subtle intervention, and/or ingenious persuasion, I'd forestall the untimely passing of Jim Henson.
