E-brake - goober up all cables and especially the funky linkage on the rear end.
Antenna - eBay, new, $20 or so.
Alignment - take the VIN to a dealer and ask if the center link has been replaced under warranty. If not, they will do so and realign for free.
Leave dent alone. I had one that was huge but never cracked the paint. Pop it out and it will - rust to follow.
Muffler - watch my post for info.
