The trinary switch is recommended to control electric fans, if you have them. If your fan is belt driven off the water pump, you only need the binary switch. IIRC, changing the switch requires you to evacuate the system, so they suggest you get the trinary switch if you plan to go with electric fans eventually.
You would only need an alternator bracket if you are not running a stock setup, or if you want to move the compressor from the driver's side to the passenger side to avoid clutter under the hood. Of course, if you do that, you won't get pre-crimped hoses. The kit assumes you are using a SBC or BBC with stock brackets. If you aren't, you'll have to cut the hoses to fit on one end, then have the ends crimped.
The sales people at Vintage Air are all very familiar with this, and can explain it to you better than I can. They can quote you part numbers and everything if you need something a little different from the norm.
