yup looks like your entire bike is stock. So I don't want to reccommend any parts that might not work on your
new frame, cause I know you want to buy a full suspension frame

So don't get new forks or stem, but get some nice new Shimano XTR V-Brakes. They will improve your stopping power tremedously and have a much smoother feel. The XTR are expensive and are a matted grey/black color(which looks really sweet), but if you want to save some dough, go with just the XT brakes. They work just as well and are just a lil heavier w/ a matte silver finish to them. Both have paralle pad systems so the pad will always contact the rim evenly for superior stopping power! Have fun and go ride.
