Adhering cultured stone
I am building a small fireplace which will house a gas insert. I've already made the frame for it using lumber and plywood. I have a few question before I move on to the next step. I want to use a construction adhesive to bond the cultured stone... in regards to the fireplace itself, the stone will be adhered to the plywood. But I also want to run the stone up the wall to the ceiling, above the mantel. What would be the best adhesive for these applications and what should I use as a backer for the wall application?... is plywood OK? I do have the option of applying the stone flat (horizontally).

Well, I hope you consulted with the code officials on the construction.
Construction adhesive should hold the stone. On the wall above the mantel what is there now? Drywall? The constriction adhesive should still work but it is only as good as the existing paint.
A trick: Where ever there is a stud put a screw below the stone that crosses that stud. This will bear the weight of that piece of stone. Maybe not all of the stones will have a screw supporting them but with a good bond pattern you should still have the stones supported by not only glue but a mechanical support.
Are you going to grout the joints? If so make sure you put the screw in enough that the grout covers the head.
