Frodo, there's nothing wrong with OEM pads if you don't mind paying far more for them from a stealership and you don't mind all the brake dust they throw off.
+1 on Textar. I just went to Pagid because they had a good deal on them when I bought my replacement rotors.
BTW, anyone reading this thread in the future should know that if you want even
better brakes on your boxster, the quick (and relatively inexpensive) way is to replace the factory brake lines with stainless steel ones found on eBay and use Super Blue fluid. It's a very noticeable difference.
