If I have a catchment that lies within zones 54 and 55 of MGA 94, should I choose one or the other for the map projection or use latitude/longitude when I set up the CatchmentSIM file?

It should not matter too much. Use the Zone that holds the majority of the catchment of interest or pick a Projection/Zone that matches the source data that you want to use when defining the DEM.

It's not recommended to use Lat/Long.
