I want some good info on removing the panels and stuff around the car. I'm new to doing this but I want to deaden the sound where I can. I think parts like firewall are intimidating and might save that for last if I do. Pretty much everything but the doors. I found enough on that but I want to get anywhere I can. Roof, trunk liner, etc. As for the carpet, do you just rip it out and reinstall?
See the Repair Manual (more info) for illustrated removal and installation procedures; start under Vehicle Interior: Interior Panels/Trim. Some of the accessory installation manuals on toyota-tech.eu also show interior disassembly, if only in summary form.
