Moveset for Torterra, Empoleon, Infernape

Torterra, Empoleon and Infernape are the most valuable pokemon of my team because I got them from the moment I started playing Pokemon Pearl. But I didn't have much time to think about their movesets, because I put most of my effort into filling my Pokedex. Now that they are almost at lv.100 and my Pokedex is completed I will write their movesets here so that you can help me create a stronger team.

Torterra lv.94
-Earthquake
-Crunch
-Leaf Storm
-Razor Leaf

Empoleon lv.95
-Drill Peck
-Hydro Pump
-Bubblebeam
-Metal Claw

Infernape lv.97
-Scratch
-Flare Blitz
-Close Combat
-Flame Wheel

I will also be grateful if you tell me your opinion about what items they should hold. Every little bit of help is appreciated.
