Well, if you have skill points to spare, I'd add that you should put 5 ranks into any skills that give synergies to your key skills. Spellcraft and Decipher Script to give synergy to Use Magic Device, if you're a Rogue; Knowledge History to give synergy to your Bardic Knowledge if you're a Bard. Also, put 5 ranks into skills that give lots of synergies in general; Bluff (which gives bonuses to Diplomacy, Disguise, Intimidate and Sleight of Hand) and Tumble (for Balance and Jump) are examples of these.
