Where do you mount the filter? After the ball valve or between just before the snubber?
As close to the snubber as possible. It can be in the hose, or anyplace.
You can use a Male/Male nipple (as you say a "sex changer" to add the filter to the system.
You do not need check valves any place in the system. The part you found is a good one, I use them for other reasons, but not on this system.
Do not remove threads to make it smaller... the threads are tapered and need to be as they are.
In my PM I offered to accept your parts and to assemble, test, and then send the system to you. Let me know if that is good for you, it will make it easy, for sure, and since I get a great FEDEX discount it will probably be cheaper too.
I am making up another system for a local guy, parts will be here next week, so I will photo it with the filter installed and you can see how I do it.
