I will certainly have to look into getting the dents done, it drives me nuts to see them.
I put two small dents in the rear quarter panel while it was parked in the garage. I put something on a shelf, and stupid me let it fall on the car.
I got an experienced guy that does PDR for a living, and he did an outstanding job. There are no signs that there was ever any damage.
Maybe find a good PDR guy for those small dents.
As for shopping mall parking, I'm anal as well. Couple of things that have helped me:
I always try for the end of the row spot, so that I only have a vehicle on one side. I cheat a little to the outside edge as well, thus leaving lots of room on the other side for any cars.
I also look for the spot next to a handicapped space. Most of the time the handicap space is unoccupied, and if it is, they are much wider, which means more space between them and me. This is my go to spot if I can find it.
Lastly, there are certain vehicles I never park next to. Pickup trucks being number one. Those massive things are horrible. You will get dinged if you park next to one of those.
I also avoid SUV's with car seats in them. That's another guarantee that their doors will be flung open by either the parents or their small kids. They don't care about what is parked next to them.
After a year and a half of ownership, I have no scratches or parking lot scuffs/dings.
