Anal, no. The 2003 has the newer AWD system and is a little more forgiving. The current spare is the same outside diameter as the OEM tires you have on it and should be good for about 30 miles or so at slower speeds - under 70.

I usually checked my pressure monthly, and rotated wheels at every oil change. My R was so low that I needed a jack to get to the drain plug anyway, might as well rotate the wheels :) Get youself a good torque wrench for the lugnuts.

Have fun with your "new" car, the ride is softer than the 700s but it also doesn't hold as much inside the rear. You will NEVER oversteer again, and the traction control will not let you understeer. Leave the AC on all of the time, and the ECC controls on auto - just set the temp at what you want.
