I put a "Skills Breakdown" section in my sheet for just this purpose
Monk skills (Initial)
Class: Diplomacy, Hide, Knowledge (religion), Move Silently
Cross-class: Balance, Climb, Concentration, Craft, Escape Artist, Jump, Knowledge (arcana), Listen, Perform, Profession, Sense Motive, Spot, Swim, Tumble
Soulknife skills: Autohypnosis, Spot, Tumble
Binder skills: Bluff, Sense Motive
Soulbow skills: Concentration, Listen
Fighter skills: Intimidate, Swim
EDIT: Ah, spotted my mistake. I misread it that you choose some of the skills granted by your class to be class skills and the others are cross-class skills. You're meant to choose any four skills, regardless of whether they're class or cross-class.
