Congrats!!!! Debt free = one huge leap towards stress free.
Yes, your hunch is correct - newer silver cube trim is a different shade. It's very noticeably darker, it will not match the older more silver trim so be careful what you buy:

Yep! It was a huge PITA for me as well. I also pull the securing grommets out every time, but I've mastered it except for that center dash pin near the steering wheel. I've probably pulled the trim out about 6-8 times now and never broke anything until yesterday.
