I also did this, but didnt do the doors cause i was being lazy, i will get to them one day, but i also replace the matting under my carpet, and did the firewall behind the dash. I did mine more to keep road noise out of the car, which it did a great job.

I mention doing this with a few beer buddies and they all sigh with excuses. I need and want to do it so badly lol. I just suck at interior work and door panels. Just not my forte....

As far as the time it took to do this what was the most time consuming part? Just picked up a 93 Firebird that squeaks and rattles like crazy and have thought about doing this. To me pulling apart the interior and laying the sound deadener seems like it would be easy, but assembling everything after could definitely be awhile for me.

Most time consuming part is cutting the material before applying it. I wanted to cover as much square footage as possible so you need to cut accurately, now X that by the 500 or so pieces you have to cut

At audio shop I worked at in college we always dynamatted the outer door skin and were careful doing the inner door shell to not cover up rivets and bolts and to retain the OE plastic vapor barrier. The results are better doing the whole inner door but you will be completely hating life when it's time to replace window motors when it's time to get to all the rivets and bolts. Ask me how I know.

I just did my car this week in class and it made a huge difference! I didn't have nearly enough material do do everything (46 sq ft) so I just did the major areas. Some day I'll go back with more and take care of the doors and all the areas I missed.

Finally finished up sound deadening my '99 TA. First off, yes it is a LOT of work. I probably put close to 40 hours in this. But at least in my opinion, it was worth it 
I chose to get 100sq feet of FatMat 100 Sq Ft x 80 mil Thick Self-Adhesive RattleTrap Sound Deadener
Here's a write up:
Make sure to keep all your screws and bolts organized when you take stuff out. I had little zip lock baggies that I used to keep track of everything.
Rear hatch area is the best place to start. Nice flat area that will get you used to working with the material.
I originally thought this was going to be a weekend project. Well Monday came around and I was only halfway done but needed to get to school. Bolted my seat in drove it like that for the remainder of the week until I finished everything up. Did get some weird looks from people
Make sure you take extra time when it comes to the speakers.
Just about done. Not the cleanest job, but made a world of difference for me. Road/wind noise is mostly gone and overall quality and feel of the car is greatly improved. Great project for anyone with a lot of spare time on their hands

I want to do trunk and doors and maybe rear quarter will if make a difference if just do some some spots?
