Shaco needs to get Jack's for his starter. Sit by blue and start stacking up Jacks. Have an ally scoot on over from bot lane to attack the minion, then go run off to his lane. All the while you should be taking advantage of your back-stab innate, and getting your blue buff quickly. Once you've gotten your blue buff, proceed jungling as normal.

One of the biggest things with Shaco is that you should build AP. Two-shiv Poison scales 1 to 1, as does his ult. Decieve should be your main form of escape/chase, and you should be baiting players into your Jacks (+400 AP = +100 damage to your jacks, 600 damage Two-shiv, 1000 damage Hallucinate on death).

Shaco's Halucinate can be controlled via alt-clicking, so you can suicide him into towers without any fear of dying yourself, as well as getting a few kills in the process. Finally, Max CDR can put your Shiv on a 5~sec cooldown, allowing you to easily harrass and punish people who get into your range.
