Honestly, I'd recommend putting a charger on it when you first get it, just to be sure its charge is completely 'topped off'. After that, yep just leave it disconnected until you start driving.

There's an 'old wives' tale about not letting it sit directly on a concrete floor, but that myth has been 'debunked' afaik.

No...at least not that I'm aware of. The procedure that Mr. Nickleye described is about as straight-forward as can be.

Generally though, an unmodified/factory/oem vehicle doesn't draw very much current at all when the vehicle is sitting. Many abnormally high current draw situations associated with prematurely dead batterys are related to mods/upgrades. I'd suggest you start the fuse-pulling exercise with any circuits associated with any aftermarket electronics modifications on your Supra, such as boost controller, fuel controller, gauges, turbo timer, security system, stereo system, etc...

So Im getting a new battery free of charge from Optima, sounds like it had a short in it. Could this have been the real problem, or do I still need to find the draw?

It's likely that was the primary problem, but if I were you I'd measure the new battery after 1 day of sitting in the car, and if it's unusually low, I'd get back on the troubleshooting path...
