Chad,
Deffo do the pads, the standard ones are like chocolate, you'll probably get fade or ruin your discs with deposit as they will just smear.
If you can't stretch to RS29's then get the PFC (Performance Friction), they are a lot cheaper than the RS29 and a worthy upgrade over OEM pads.
They are cheap too:

Ferodo DS1.11 are as good as RS29, cheaper than RS29, but more expensive than PFC:
