Wow, that's a bunch of questions since my absence, I hope to answer them all.

HUFA = Highly Unsaturated Fatty Acids.

Glass and Ghost shrimp are usually the same being that is a common name and not the species name.

Gut loading is when you take a live food item such as the glass shrimp (which have no real nutritional value) and allow them to stuff themselves eating as much of a good food source as possible and then feeding them to your livestock.

DT's is a brand of phytoplankton that is a valuable for many of the creatures we keep.

I'm not sure about crawfish, I'd rather stick to shellfish or clams from the seafood deli to ensure the proper nutrients and not adding saturated fats as with fresh water fish. Saturated fats cannot be digested properly by marine fish.
