(if no one here wants to go into it i'll go ask in the 'Mechanics' forum) and not only adjust it but how do i know how far i can pull it up safely? I'm going to see if i can find new brake pads today. also i will adjust the seat to a more level position.
Thanks for all the help.

To raise your existing stem unscrew the bolt on the top of the stem about 4 or 5 turns. Then use a plastic hammer or a board and a steel hammer to tap it straight down. That'll unseat the wedge at the bottom of the stem and, if all goes right, will allow you to pull the stem straight up. The back of the stem facing the rider will have a minimum insertion mark engraved into it. Don't "cheat" on that unless you have really good dental coverage.
70mm is a really, short front-to-back stem extension. Not what I would recommend. For comparison, the one that you have now is probably 110mm.
