Lucky to have the 350 as your first car!
Anyhow, since the issue appears to be with the brakes, I'd take it somewhere that will offer you a free brake inspection. Ask them while it is up on the rack to show you any issues they see (aka worn rotors, worn pads, etc). ALSO, while it is up on the rack, take a look for yourself at other aspects of the car to take advantage of the use of their rack. Check for leaking shocks, leaking exhaust joints, worn tires, leaks (trans/engine/rear-end), etc.
GL and you WILL enjoy the ride! BTW, 80k isn't high-mileage for a Toyota.
