I can answer all these questions. TR; Tuner ready, basically a "no frills' WRX, that is kept cheaper by not being loaded up with a bunch of options. Therefor, the buyer of the TR, has more capital to work with in molding the car to how he/she wants it.
As for the transmissions on the 02/03's. They do have a rep for being fragile. They don't do well, with 300+ awhp, and hard launches, i.e; 5500+ rpm. The cheapest route to more strength, is the RA gearset. It's about $1600-$1800.00, another 6-$700.00, to have it installed. The more prefered route (but considerably more $$$) is a full STi drivetrain swap, 6-speed gearbox, diff's and axles along with the driveshaft. I don't know about the GC swap, but I do recall some guys talking about that at a local Subie shop.
Rear seat room is better than our Supra's, but not luxury car standards, by any means!
Hope that helps you.
My son has a mildly modded 02WRX "Bugeye". Still going strong with 101K+ miles on the odometer!
