Hi Echo, welcome to Ironworks.
As for the gear, if you have associated the CEP with your sp games, you can simply export your char, and use it in the campaigns. If not, you can still use the toolset to make your own gear, and place it in a practice mod. Load the practice mod, and go get it...Easy.
This is why Undermountain is a server vault now, too many people making uber munchkins, and running around like it was a cake walk, at least that is one of the reasons, as I understand it...
