i used 28mm gp4000II and would do so again! Great tires -fast, grippy, durable and comfortable. I might consider replacing them at some point during the race, though. I find they are good at avoiding punctures up to a certain point, but once they've worn beyond this, you'll get quite a few.
IMV re pedals - use what you're comfy with and take spare cleats. Comfort for pedalling > comfort for walking.
