The popping noise you're referring to is likely the weatherstripping. You could put a little lube of some kind on it to keep the stripping from sticking together and popping when you open the doors.
As for the squeak, I had this too. I removed the seat and all the plastic trim around the seat frame and WD-40'd and all is well. Lasted about 6 months so far...
