The first few films on your list are just the Gamera films from Shout's double features, but much worse quality, and only containing the U.S. versions. You will definitely want to pass on those.
-GAMERA VS. VIRAS is the same movie as DESTROY ALL PLANETS
-WAR OF THE MONSTERS is GAMERA VS. GYOAS
-ATTACK OF THE MONSTERS is GAMERA VS. GUIRON.
Also, GUYVER 2 is horrendous, just a forewarning. REBIRTH OF MOTHRA III isn't available on DVD in the U.S. Lastly, Critereon's GODZILLA release won't be out until January.
