OP, the shifter bushings, like the ones provided by Turn In Concepts' Holy Shift Kit, will help with precise shifts in day to day driving. I've got it installed on mine with Cobb's Adjustable Short Throw.
For the problems you encountered during the hard launch, you need to upgrade the Pitch Stopper, LH/RH Engine Mounts, Transmission Mount, and transmission crossmember bushings to prevent lateral movement. The stock mounts are made of soft, pliable rubber which allows for quite a bit of movement under load. I use Group N mounts in mine. They're stiffer than OEM, but not so stiff that the car rattles itself to death.
If you have been driving manuals for 10 years, then you should know what a burnt clutch smells like. Revmatching and launch control should help your clutch last a little longer.
