WRX Timing Belt - What else to do at the same time?

[JohnC]

I'll be changing the timing belt in our WRX soon. The service manual just says "replace timing belt". I remember for the Z, there was a whole list of additional parts to replace if you were doing the timing belt. Do any of the other Subaru guys here have suggestions?

If the answer is "just replace the timing belt, because Subarus don't make you hate yourself like Z32s do", then thats wonderful...
