Problem number two
On the DIC I keep getting "right rear tire over inflated"
I check the tires and they are ok...around 32-35 lbs but the message keep popping up. Is there a way to clear it? Is is there something wrong with one of my sensors?

odd.
Are you checking the tire when they are hot or cold, when they are hot they expand and the psi gets lower (but not the true psi), which may seem normal to you. Check the tires before you go for a drive in the morning while they are still cold that the true temperture.
If its normal then it might be a sensor, but play with it for a minute, take out 3 psi and see if its still going off. Take out 10 psi and see if its still going off. If it is then the sensors messed up, just inflate back to what you want it to be at and schedule a appt. with the dealer.

Actually, as a tire heats up, the tire pressure increases, not decreases. The air expands (or wants too but cannot) a lot more than the tire when heated so the pressure rises. That makes more sense with your warning - you measure the pressure when cold and all seems fine, but when you drive a while the air pressure increases (apparently too much) and causes high pressure warning.
Outside temperature makes a big difference here, too.
However, if you see the warning and immediately stop the car and check the pressure with a tire gauge, you should get the same reading on the gauge as the car told you. If not, you either have a bad tire gauge or the pressure senser in the tire is not reading correctly.

What does the sensor in the DIC say as far as the acutal pressure value? (not withstanding the high pressure error).
If it is showing as higher than your manual guage reads, two things could be happening.
The sensor could be bad or it needs to be reset/retrained. I don't know if the C6 retraining procedure is the same as the C5 but the procedure for C5s is listed in the tech tips section.
I don't have a C6 so maybe I'm completely wrong, but that's how I'd approach the same problem on my C5.

The owner's manual (p 5-61) says that a warning message will appear on the DIC if a tire is underinflated (falls below 24 psi) or overinflated (above 42 psi). Even if you're running 35 psi, that's 7 psi under the limit. Sounds like a sensor might be bad in that tire. Don't think you'll see more than 3 or 4 psi added or subtracted for cold vs hot tires.

This sounds like a bad sensor but I would do the tire training first before dismounting the tire and replacing the sensor.

First of all make sure your tire gauge is working properly and set your inflation to 30 cold just like the sticker says. Then once you have checked the inflation, see what the DIC says the pressure is. It should be 30. If not then the sensor needs to be be replaced. Do not over inflate or under inflate.

Nitrolgen is not suppose to expand

A Nitrogen-Filled Tire? Why?

I don't really understand what you are saying here, but did you know that air is more than 78% pure Nitrogen? Alomost all the rest of air is Oxygen (20%) which weighs and behaves almost the same as Nitrogen. So I doubt you will get any measurable difference or perfomance between an air-filled tire and a Nitrogen-filled tire.
I have never heard of a Nitrogen-only-filled tire. Is this common practice? If so, can someone tell me why? It won't be much different that air, so I don't understand...
