How does this setup sound to you?
in my opinion do gears now preferably 3.73s. have fun with them for awhile. then if your set on a stall go for it. i think if you just stick a stock trans mount in there and stick some gears in it your gonna have a blast with it.

Engine mounts are a beast themselves, but are much easier to do when swapping headers in. I can't remember if you mentioned that you already have headers in or are going to have them put in, but strongly consider going to poly motor mounts while installing headers. It's by far the easiest time to do them.
ANSWER THESE QUESTIONS:
1: What is your rear end gear ratio?
2: How many miles are on this car?
3: What is the condition of the transmission?
If you want more experienced people here to assist you, you need to answer their questions so they can better assess your situation to offer more accurate advice.
EDIT: My bad, I see you've posted 107K miles. Sometimes I suffer from O.L.D.

Also, if you are on stock mounts, with 107,xxx miles on them, and they are not in great shape, don't put on the poly trans mount. You want your trans mount to give more than your engine and not the other way around.
To me it seems like you are getting very bad advice from these "experts" and turning a deaf ear to people who have first hand experience on these subjects.
Sometimes, you just can't teach or guide people, you gotta sit back and watch them learn on their own from their own mistakes rather than listening to good advise from those who've been there, done that and know better.
To the OP:
We're gonna continue trying to help you but you gotta work with us man.
Four easy ways to get the rear ratio:
Turn the drive shaft by hand with the rear wheels off the ground. For a single complete wheel rotation, how many times does the drive shaft turn?
OR
Get the G code off the door sticker. GU2 = 2.73, GU5 = 3.23 and GU6 = 3.42
OR
Get the VIN and plug it into the compnine website and find the G code.
OR
Post your VIN here and we'll plug it into the compnine website.
While you're under the car, tell us if it's a steel or aluminum drive shaft. Not sure? Try sticking a magnet to it.
as far as the gears go we will need to know for a suggestion but unless your car is a ws6 im more than willing to bet its got 2.73's in which case going to 3.73's will make your car feel like you always have nitrous on its pretty wicked at first not gonna lie. just make sure someone sets them up that knows what theyre doing or theyll burn your nice new set of gears up.
after the headers make sure you get an xpipe or something in reality an xpipe performs similar to an offroad y pipe at stockish levels but an xpipe sounds way more badass
1998 Trans Am (from this point on it was ran HARD by me on a daily basis)
100K miles- 4400 converter ms4 cam LTs Xpipe 1 chambers
105K miles- 410s rear end girdle ported 90/90 FAST intake setup
110K miles-PRC stg 1 ls6 heads
116K miles- sold and still running like a champ to this day
I ran it hard... And I mean hard. WOT daily and PLENTY of hot laps at the track. Trans never missed a beat.
If you can't get a converter, stop modding it. Put a big cooler in it and a retune and don't worry about it. If it goes, it was going to go anywhere, PERIOD.
273s- consider an upgrade to 342s (I wouldn't)
323s- stick with stock gears until you upgrade rear ends then go 373s
Mods listed in first post- high 12s (mid 12s possible and low 13s possible all depends on weather and traction)
With a good converter- bottom 12s

False.
