Any planning or reccomendations for a 55...
A dogface puffer is not a problem as it does not have spikes and is sociable to other fishes in the reservoir thus its alright for them to be together
Crab feed problem?
Answers:    I've kept puffers and tangs and clowns, you want to be sure the clown is larger than the puffer. THere really shouldn't be a problem as long as your puffer is not LARGE.

Also, how long has your tank be up and running? If it is less than 6 months, I would watch at this point getting the puffer until your tank mature a bit more. Live rocks, corals shrimp also a no no with the puffer.
