For Metagross, replace Shadow Ball with Earthquake. A STAB Meteor Mash will do nearly the same amount of damage as Shadow Ball will to things such as Gengar. Earthquake allows you to cover Fire and Electric types which resist Metagross's STAB attack. I'd also recommend that you use a 160 HP / 252 Atk / 96 Spe on Metagross.

For Skarmory, I would recommend you use Hidden Power Flying with Whirlwind, so you can screw over Mr. Mime based Baton Pass teams. Use the spread 252 HP / 156 Def / 100 Spe. This will allow you to outpace the standard Tyranitar with Dragon Dance before it Dragon Dances.
