Hard to say re the TPS - I wouldn't worry about it unless it comes on again, in which case I'd take it in to have the dealer check the sensors (assuming the pressures are OK).
Check the raised lettering on the side of one of your tires. If it says 215/40ZR18 on a front tire or 245/35ZR18 on a rear, you have summer performance tires and should inflate to 36 lbs. all around. If it says 205/50HR17 (front or rear), you have all-seasons and should inflate to 33 front, 36 rear.
Incidentally, if you have the 18" summer tires, don't drive in temperatures much below freezing and avoid snow and ice at all costs.
