Yeah, looks like there are some good ones. Remove any which are thin/hollow, if they are firm then leaev them. You have some which look brown but firm (as far as I can tell) leave those, they looked stained rather than dead.
The majority of people in the USA seem to like potting in bark mixes. Some like moss but many find that leaves things too wet.
Personally I would advise getting hold of some good quality orchid bark
www.repotme.com have some good ones. Be careful about ones from a local store as they are often already too decayed before you start.
In the mean time unless the moss smells bad tuck it back in with the moss, but don't back it too tight. If you don't use all of what it was in before don't worry. It should be firm enough to not wobble everywhere, but not so tight that no air gets in.
If you decide to keep it in moss rather than bark I would still advise looking at the above website to get fresh stuff, moss needs replacing at least once a year.
