You can run a stock tune with intake and exhaust. Your car is excessively rich from the factory, thats why we gain so much from just a tune. If you add the intake and exhaust and slowly work up to WOT letting the ECU dial in the trim, you will be fine. if you hear clicking noise then back off the throttle and let the trim catch up
The o2 sensors will pick up the subtle change in the mixture and adjust accordingly. Its not like you are drastically changing your cams, heads and porting the snot and expecting the ECU to keep up.
I don't think the intake can void your waranty unless that's what causes the problem on your car when you take it in for warranty. Most dealerships are cool with this from my experience.

I agree, YMMV, but from stock I installed an intake and then 3 weeks later an exhaust and starting at stock the car idled mint and ran perfect. I noticed no trouble. With the air intake installed I noticed the engine would sometimes slightly rev itself and fight the brakes. Maybe this happened before? Maybe it didn't. Keep in mind that k&n filters come with oil on them and have been seen to cause MAF cleanliness issues. Like I said about the idle blips..
Also, I cleaned the filter with the recharge kit and lightly applied filter oil to it so that it contained a reduced amount of oil and now is less likely to contaminate the MAF. I haven't had a problem since.

See above. Air raid offers two filters, bringing us back to the whole oiled filter vs. non-oiled filter argument. I prefer k&n.

Re: AIR RAID or D3 intake
As another data point, I installed an Airaid in my 2012 CTS-V automatic with no tune and it's been awesome. Noticeable performance improvement, great supercharger whine, and zero codes, check engine lights, etc. The engine loves gulping that additional air.
