You want to be positioned just right so that you ride as efficiently as possible. You may find that you also need a different length or rise stem, or your saddle is too far forward, etc. If you've never been fitted on this bike, then that probably the best thing that you could do.
For better braking, replace your stock Shimano brake pads with those from Kool Stop (I'm assuming that you're using the stock pads). The reddish color KoolStop's are excellent all around pads and may improve your braking markedly for about $17-18.
After this, there's nothing more that you can practically do short of buying a new bike. your Rockhopper is nice, but not worth the expense of all the upgrades you mention- in fact, you're frame probably isn't even disk-compatable, effectively killing that as an upgrade option.
The frame is disc compatible, I just didnt realize how much wheelsets cost.
