Yep, that is it. DGV is manual choke, DGEV is electric choke (about the easiest to deal with) and DGAV is a water choke you have to pipe engine coolant up to and back out of. The 38 DGES you may have seen is basically like a 32/36 DGV only with both holes a bit bigger and primary and secondary are syncronous instead of progressive as they are on the DGV.
The big advantage of getting the kit from someplace like
http://www.carbs.net is that you get the whole shebang (minus something to hold the cable I believe, but that isn't hard to fab up) and don't have to track down gaskets and an adapter plate. Not to mention something for an air filter. The adapter plate on its own can run $50 depending on where you can find it sold seperate, and the carb will not bolt right to the stock intake on a LUV.
You also may get different jetting in the carb depending on what it was sold to go into. The kit for the LUV will have jets pretty close to what you'd want unless you've got a cam and other mods. Pretty close is well within the adjustments on the carb, but too much or too little jets and you will have trouble getting the carb dialed in to run just right.
