What kinda blade do you think would work for cutting one side flat?
Give it a rip. I don't know what your blade is, but a cheap angle grinder blade (one of those diamond coated things that are less than 10 bucks) would easily do the job, too. If you have a tile saw already that has decent cut depth, and water, might as well use it.

If anyone else reads this and uses an angle grinder, always use a mask or a very wet sponge held against the diamond blade during the cut (like sopping wet) to make sure you're not breathing the dust. When I worked for a tile contractor, that's how we cut our runs of tile when we were inside a building (or really anywhere), a large sponge totally soaked, and the dust runs away in a slurry instead of getting dispensed into the air. Just score or mark a stone before the cut is started so that you have a guide to go by and end up with a nice even cut.

As far as plaster of paris, that's sort of a guess. A lot of the old irregular stones I've had have been bedded in plaster. The type of plaster it is, I don't know, but plaster of paris should work well and it's cheap and quick.
