CORRECT YES
CORRECTThe connections displayed here agree with the connections I plan to make. YES
INCORRECTThe pinout for the compact flash connector is ambiguous. It is not keyed, and therefore impossible to tell the top from bottom. YES
CORRECTI spent a lot of time while dismantled CF and checked key assigment. Finally i found simple solution what works- so here is Tip how to know which keys are 1-25 and 26-50:
It is known that CF keys 1, 25, 26, 50 is grounded (still mirror riddle) and only one more grounded key 33 is answer. If you look picture how Female connector looks, then key 33 is 8ht hole from left in upper-row. Now just get a chain-link using your resistance-tester for any key 1, 25, 26 or 50 to this 8ght hole by turning CF card upsidedown. When you got link, then you know where is key 33, so left is 26, right is 50 and down-left is 1 and down-right is 25. Note: use picture from this side for pin assigment. 
YES
