Any good wax works Dean. Just get temperature specific and a hot wax will always be better and last longer than a quick rub!

Sharpening really is a skill every skier should learn because it is very personal to your skiing style. Basically though, you want the tips and tails sharpest with under foot less so. You don't want burrs so get a stone to remove those. The hardest edge to tune yourself is the bottom. If you find the file is mainly hitting the middle of the ski, it is time to bottom grind. The vertical edge really sets the overall sharpness of the ski, but takes some steady hands. For me, I like really sharp skis. You should be able to run your fingernail perpendicular to the edge and slightly shave the nail without effort - but that's just me.
