It's really up to you and which options appeal to you the most. I would agree that the Z51 package is a must for most people. I'd also definitely recommend the performance exhaust to make it sound like a true sports car. After that it's your call.
I was originally planning on getting a 1LT Z51 but recently changed my mind to the 2LT Z51. It adds a lot of the bells and whistles that I know I'll love.
