I have a 07 GQ with 12k miles. New tires last year, SS run flats, oil changed every year. Also have had clutch, and brake fluid drained and replaced in 2014. Coolant drained and filled last year.
All done at a dealer by a "corvette tech" along with a visual inspection and tightening of Corsa mufflers.

The dealer truly messed up the tires, installed the wrong ones, SS non run flats on the rear, and AS3 on the front! Thus will not be going back.

What other preventative service needs to be done with such low mileage, but 9 years of age? Belts and hoses? Tranny, differential? Open to suggestions, and also Cleveland area dealer for service, Tim Lally maybe?

I'm not sure that I would do anything else that was not covered, but want to make sure that the hoses are flexible and not hard by giving them a squeeze and noting any weak spots. Hoses usually fail right after the joint at attachment points.
BTY, you coolant was a little everdue, the norm for dex-cool is 5 years.

12,000 on an 07, Wow, I just don't understand that kind of thing. (Not saying its bad, I just don't get it) My 07 has 130,000+ on it and gets more every day! It's the most fun car I've ever owned !! Other than normal maintenance items, such as oil/filter changes every 6-7k, tires, batteries, brakes, belts, all scheduled fluid changes, spark plugs, etc the only repairs have been 1 fuel level sensor (Warranty work) one starter motor at 110,000 and I just replaced the radiator due to a small crack in one of the tubes. It runs like a champ and still gets 29+ MPG at 70MPH.
Of course, its not perfect now by any means, The passenger side visor cover broke off a long time ago! It has road chips as you would expect in the paint, and the XM radio contract expired a long time ago I have owned it since new and can account for every smile delivering mile on it. I look forward to driving it every day, I get a little disappointed when my wife wants us to take the SUV to the grocery store etc, I understand it, but I don't like it Any way, good luck with your car, take care of it like the service manual says at a minimum, Then just enjoy it, (In your case more than you have been)

Have you ever replace the sway bar end links and the shocks?

HBsurfer

You already have most of it handled. Diff fluid should be replaced (easy DIY). If the car clunks over bumps, replace the end links (easy DIY). Air filters (2) and cabin filter. Take a looks at the belts to make sure they are not cracking (probably fine).
Most important thing you can do for that car is to put some miles on it.

Maybe replace the differential fluid as some Vettes had clutch pack chatter from the fluid they were putting in it back then. I would'nt worry about the transmission fluid until 30,000 miles. With that mileage your end links shoud be fine unless they are dry rotted. My guess is it's not likely. Inspecting the coolant hoses and accessory belts is a good idea.

I replaced the sway bar ends with spherical rod ends just because I had them available, the shocks are still the factory Z51 units, they still work fine, no issues with them at all.

HOXXOH

At 12K miles on a 9 year old car, it's been over-maintained and under-driven. You might as well drive it at the same rate until something breaks, which might not happen in your lifetime.

I think I would go back just one more time brother.
