I'm trying to reprofile for the first time. I have a Spyderco Sharpmaker and I went out and bought 220, 400, 800, 1000, 2000 grit sandpaper. I'm going to be reprofiling my Blur down to a 30 degree edge. What I'm wondering is how many strokes I should be doing on each grit? Also, Where do the stock Sharpmaker stones fall into those grits?

Sounds like you need to do some more reading here, my friend. But I'll be nice 
You want to start on your coarsest grit and sharpen until you are forming an even burr along the entire edge (as well as the opposite edge, when you switch sides). Then you're ready to move up to the next grit. From here on out all you are doing is refining the edge, the bevel and the burr. You want to remain on the same grit until you've removed all traces of the previous grit. As you go finer and finer the burr will get smaller and the edge and bevel will become better polished.
I'm very sure others here can say it better, so don't stop reading at my post, and don't be afraid to browse and search the forums!

Agreed.
I've been a machinist for many years, so am pretty skilled at hand-sharpening tools, and there are some knives that I won't even touch without a jig as far as sharpening goes.
Sometimes the blade grind, thumbstuds, blade thickness, angles, etc. leave VERY little room for error if you are worried about a perfect job.

Reprofiling with a SM???
Eat a good lunch, take a short nap, and prepare to work late into the evening, and/or several evenings.
Seriously, the SM is a wonderful tool for "touching up" an already sharp knife, but it's utility for serious re-sharpening and/or reprofiling is somewhat limited.
