tri shoes?

I'm doing my first (sprint) triathlon at the end of August, and I have a question regarding shoes. Should I use my clipless pedals for the bike, then switch to running shoes for the run? Or should I wear my running shoes for the bike ride (I would need to get some non-clipless pedals)?

I can't find anywhere online that tells me what's best. For a full-length tri, I would assume that clipless pedals are recommended. But since this is so short, transition time is really important, so would it just be a waste of time to have to change shoes from the bike to the run?

Thanks!

Note: I just bought some PowerGrips online. Anyone have any thoughts?

Power Grips are perfect for a Sprint Tri, several triathletes in my town are using them.
