Whole slug of questions here.

In answer to your Valve queries. Regular valve is just a spool valve. Different ones for Closed center and Open center. Also and more importantly different ones or set ups for one way and two way cylinders.

Float is just a different position on a spool valve that opens both work ports to the return allowing the cylinder to find it's own level. Just need to get a valve with float.

Now to the application of the 3Point. For that you will probably want a 1 way cylinder. That being that pressure is only applied in one direction and gravity makes it go the other way. Will probably need to have the other side of the cylinders go to the resivoir as you will run out of oil unless you are putting on a stand alone hydraulic setup.

Now to your specific tractor. The VA series had two different hydraulic setups. One drove off the belt pulley shaft and the other drove off the engine. Usually the one driven off the engine was for tractors with Eagle Hitch in which case all you need to do is make things so the arms can swing. The Belt pulley drive has the valve built in and only needs the cylinder.

ONE NOTE If your tractor is actually a V or VC instead of VA or VAC I wouldn't even think about adding a three point. These are a fairly rare tractor and you would be well advised to trade it to a Case Collector for a 8N ford or the like. Easy way to tell them apart is the V and VC used a Continental flat heat engine and the VA and VAC used a Case Valve in head engine.
