First off, don't spend the money for the hose kit which will power the BH. You have to crawl under the tractor to turn the valve each time. If set to power the BH, your 3pt won't work and if hst drive, it won't move very well until reset. It's about half the cost, $175 for the kit, but just gives you one way hydraulic fluid power without any control; no control lever.
The first remote is all you need to power the BH. Cost $275 for the kit. You'll have a control lever so you can connect any type of hydraulic item, log splitter, tilt cylinders for the 3pt, or anything else you want. One position of the valve has a detent which you would use for the BH to give it constant flow. Otherwise you can control the out flow to either fitting.
The second remote is primarily the same but one position has a float function like a FL if you have one. Second valve cost $375 for the kit. If you need to control two things at once, put on both valves. Otherwise, the first valve is all you need. If later, you decide you need both remotes, the second can be added on. Other than the extra labor, the kit price is the same and contains all you need.
This is from my experience with first having the hose kit for my BH. I personally installed both remotes in at the same time to save a little of my labor because of planning to add top and tilt cylinders to the 3pt. Not to hard to install and will save you a few dollars. I had posted a few pictures of the install back in April. The instructions supplied leave a few questions which I can help you with if needed.
