Definately get the PASM. Its by far the best ride of any car I've owned (BMW 330Ci, C5 Corvette). In normal mode the car turns and rides completely flat, but is softer over bumps than both of the other cars. In sport mode it firms up and is ideal for track day use.
BTW, this is on 19's.
Also get:
heated seats - extends topless season.
rear trunk liner tray - makes for easy cleanup of spilled take-out food when it tips after carving the twisties on the way home
xenon headlights - obvious
rain-sensor - can't live without in Seattle
Don't waste money on wind deflector - it barely makes a difference and creates distracting headlight reflections at night making you think a car is in a lane (that you're trying to switch to) when there really isn't.
