Boog first of all get that 2500 Psi relief out of there that is why the key sheered off. The 1206 would have had no more than 1800 PSI relief and that was very good for the 1206, most likley the relief was not at full pressure, because the 2500 PSI would lift the bat wing, if 1800 PSI will not lift the bat wing put on bigger cylinder. Now for the setteling, you said the 3 point and mower both. If that is the case then you have 2 problems. First if the mower is setteling that is either in the cylinder leaking buy the ram oring or leaking by the remote valve on the tractor in which case you could put on a check valve on the tractor to stop the mower from going down. As for the three point hitch if it is setteling with the engine off you have a leak in side the rear end in the hitch hydraulics. Could be the cylinder seal could be oring where the valves goes on the cylinder, could be the valve and then could be the coushion relief valve leaking. A lot of people thing it could be oring some place as you said at the pump or a long the system some place or relief valve, but once the oil as been pumped into the cylinder as on the mower or into the hitch everything before the valve is no out of the loop and only the valve and cylinder and related parts between valve and cylinder can cause setteling. As for lifting only at high RPM's you will have to check the pump to see if it is pumping 12 GPM.
