As for skills, I personally do fire, ice, gale, clock and lightning. I swap clock for lightning at boss.
Again, mage is a pretty versatile class, so it's really down to preference and play style. I know many mages who would prefer having shield instead of all attack skills.

Honestly, ask him to prepare a few respec kit and try out various builds. Different players will have different play style and builds.
