Overall good advice CR, but I have to comment on a few things:
If these are your first brand new pair of skis I STRONGLY recommend paying someone else to mount them. Once you have have seen how they are supposed to look and have an example handy to reference pick up a pair of rock skis (used skis that have some wear) and try mounting them yourself.
I agree with this suggestion 100%. At the very least, buy a pair of cheap used skis to practice on before you mount up a brand new pair.
I did most of mine myself with no jig and no template. I haven't done any adjustable ones with a demo track yet though. A drill with a torque settings might help keep you from stripping the holes and creating "spinners".. that is what you can fix with the heli coils if need be.
Don't ever screw bindings down using a drill. Screw them down by hand and you won't strip any of the holes.
I CAREFULLY drill the holes and mount the toe pieces. Use some epoxy in the holes before sinking the screws. If you're a carpenter you know how to tape a drill bit or make a block to keep it from going too deep.
Don't use epoxy in binding holes unless it's a very slow curing epoxy. Epoxy generates heat as it cures and can damage some ski cores. I prefer to use standard wood glue. Another negative of epoxy is that it's very strong and will make un-mounting the binding a pain in the future.
