When I start my SC after it's been sitting, like all night or all day, if I don't blip the gas pedal once, it idles very roughly. And it will idle with a bad case of the shakes until I blip the gas once. If I hit the gas pedal once, just a blip, before I turn the key or as I turn the key, it starts and idles fine. What the heck is going on?

Sounds like a sticky or bad IAC. It is located on the side of your TB.
