If i have a target initial velocity for a pebble i want to slingshot, how do i determine how far back to pull the slingshot? it must depend on the rubber band, right, sort of like the spring constant?

Very much so.
I would recommend measuring the pull with a Newtons-calibrated spring scale. That tells you how hard it pulls at various angles.

That sounds like a simple enough question, but in fact, it involves a lot of math.
You need to compute the potential energy of the sling shot at a certain pull distance (probably using a pull scale) and match it to the mass and initial volocity (kenetic energy) you require for the pebble.
Have fun with that one.
