Given three points, (x1, y1, z1) (x2, y2, z2) (x3, y3, z3)
and given a point "A" at (x, y), how would I find "A'", at (x, y, z)?

Depending on the library or technology you are working with - things can get easier. But it is almost always good to understand the maths behind this stuff. Have a look at the line through plane equations on Wikipedia.
