Advice on an interior firewall/flooring and assembly needed for a 66

[msg]

I am currently trying to get my brakes redone as I rebuild, but the interior has not been finished out. I was about to bolt up the booster to the firewall and get started installing lines and such and realized that there is additional steering column bracketry going on and I think I need to install first since the booster bolts to the interior bracket through the firewall. So what I am wondering is whether I need to have the firewall interior and under dash done first? From the pics I took during the teardown there is a good bit of jute padding and a cardboard looking fasten on cover as well. My plan was to use the Noico sound deadener I bought years back when I was doing the inside of the doors. I have some left over and thought to order more and finish out just the flooring and in the end carpet the floor.

So far I havent given alot of thought to the jute padding in combination with the Noico sound deadener, maybe the jutes not needed? Just use the sound deadener all up under the dash? I the firewall cover a must you think?

Also if there is any lessons learned you guys have about redoing the interior firewall and what to install first, what not to do that kinda thing I would appreciate it.

Ill attach some pics of the teardown and where it is now. Starting with what it looks like now.
