RevX is only indicated if you switch oil and still have stiction. I wouldn't add it until you give the new oil a few days first to see how much difference it makes. Since you already added the RevX, then next oil change, hold off on the RevX until you see what it's like after the oil change.
The filter and oil are changed at the same time, opinions vary between 5k and 7500. Seems like a lot of folks are having their oil analyzed but I'll just go with the flow myself, 5k for me. Motorcraft filters only for oil, fuel and air.
There's a significant amount of old oil that remains after a drain, so it takes several oil changes to completely change the oil. You may find you don't need RevX after a time or two.
