A very smart move to make a list of your requirements. The only thing I would change is the GVWR rating. I think the higher the rating the better. You wan't to make sure the actual weight of the unit is within your TV ratings but a higher GVWR may mean the suspension isn't as close to being over loaded.
An example is my own TT. Its GVWR give me nearly two tons of CCC - meaning the trailer only weighs in a bit over 7k even though its GVWR is 11,700 lbs. I never have to worry about the trailers suspension or tires being over loaded.
So don't be overly concerned about GVWR as much as what the unit actually weighs.
FWIW, my requirements would include a CCC of at least 1000 pounds with 2000 being preferred.
