All the belays are fully bolted (generally 2 u bolts) but a couple are 1FH/1U so maybe take a few spare biners to leave on the way down. From memory you can rap it on a single 60m apart from one pitch near the bottom as the pitch lengths described are generally 5-10m longer than the pitches actually are. 2 ropes is probably a safer way of climbing these routes anyway though.
The trad gear is just for climbing and is only needed on easy ground. Rapping the route you should be able to stay into the wall with just the bolts and have the second person down retrieve the draws.
