Removing Stickers from Tint

I was wondering if anyone has some tricks for this? I have tint on ALL windows, and have some stickers from my old apartment complex. I want to take them off (one is in the back and one is inside the windshield), but I am afraid to screw with them and jack up the tint. I tried a search, but I haven't found anything.
Also, there is a chip in my windshield (damn rocks) that I want to get the bubble trick done. I have had it done on other cars, but never the Camaro. Will the heat from bubble they use to fill it jack up the tint?

My guess would be complete tint replacement. And I think the tint would bubble up with the heat from the windshield repair.

damn, that is what I was afraid of. Have you or anyone else you know ever had to deal with this?
