I always advise people to bag and label fasteners and such, especially on the first run through, for most jobs to make life easier. Also be careful with small hoses that are pretty old and prone to cracking or splitting.
I concur; it's immensely helpful if you take lots of pictures as you go, and you bag and label parts as luigisho recommends. A set of hose gripper pliers is a good thing to have; cheap at Harbor Freight.
