I am concerned with the SC needing premium gas. Is it an absolute necessity? In addition, will the SC only be able to be warranty serviced at the dealership it was bought at or will any Chrysler dealer be able to work on it?

Remember, Chrysler is no longer part of the parent company and has no ties to smart unless the dealer also happens to be a smart dealer.
IMHO - Stick with the premium gas....the engine will run better and your mileage will also be at it's best. We're only talking a difference of $2 or so per fill-up. For me that's once a week. I would expect only Authorized MB and Smart dealers (all, not just the one where you bought it)can do warranty work.
Seconding what SmartBob said, stick with premium. It's a small, higher compression engine that doesn't have blinding performance from the start. Don't impair it further with regular gas. Only two bucks more per tank...oh wait, two bucks would've filled up my car back when I started driving - of course, I was only making $1/hour then too.

The mileage will be better for sure as a result of the engine running at it's best due to the fact that it has been designed to run on premium with it's compression ratio what it is. I've argued with so many people that opt to attempt to save a buck or so and they don't seem to understand that they are losing more than that in mileage results.
The Joisey guy from Pa knows what he's talking about!! LOL
We will find out if it matters after we get the car I will certainly run 87, 90, 93 oct. to see and some one will run some dino pulls on different grade fuels to see if the engine cares.
Modern engines have knock sensors that retard ignition automatically, if the fuel burn expands to fast it retards ignition to prevent exessive combustion pressures preventing any damage to the engine.
If ignition gets retarded significantly you may loose power and fuel efficiency.

I found that to be true on my cross country trip. I ran regular, mid grade and premium from different stations all the way across. Power was limited with the regular (we were driving pretty fast and heavy footed the whole triip). No pinging at all, but the electronics were probably helping with that. Everything will change with the new Mitsu engines, though. But I trust the MB engineers to know what's best.
Higher octane or premium fuel does not increase your mileage. Premium fuel is nothing more than higher octane and some extra detergents which may keep your engine cleaner in the long run. Not sure if a clean engine is really worth the extra expense of premium.
If you dont have any pinging or knocking with the cheap stuff use it. Most cars will run on the cheap stuff just fine. After all we are not talking a high performance engine here. You will not get any more performance or horse power by using premium just premium expense. If you know nothing about an engine or what knocking or pinging is just use what the manufacture recommends.
Hmmmm...I beg to differ. I've experimented with my Neon several times. It has a higher performance engine 9.6:1 comp. recommending at 89 octane. If I go higher I definitely get more miles on a fill up. An engine that was designed for high octane should get high octane. If not than yes, higher won't matter.
