Depends on what you're doing with them really.
You can go the expensive route and get some Norton Blaze ceramic grit belts for $10 per belt.
Or get some cheap Powertec belts that last half as long, but are 1/5th the price.
As far as grits go, I look at it like this:
36 grit - good for removing tons of material, leaves giant, giant marks though.
80 grit - a good point to start when removing material.
120 grit - good for removing a fair amount of metal, leaves a basically acceptable surface finish
400 grit - doesn't remove a ton of metal, but leaves a nice finish.
800-1200 grit - good for final sharpening steps.
Micron range - black, green and then white buffing compounds, in order of decreasing roughness - good for mirror polishes. I usually don't go past 400 grit if I am going to use the buffer on something, as higher grits past 400 don't seem to make much if any difference in how long it takes to buff something smooth.
