Well after 5 hours you are doing Ok, as for 2 of those hours you will just have been a passenger.
I also had the rudder problem, and being an engineer, I used to think out all the linkages … Push on that pedal, it tightens that cable, which pulls that bell-crank, which pulls that way on the rudder, which makes the air push the tail in the opposite direction.... All too much of a long winded thought process to be of any use.
As for the Yoke, make sure you have trimmed the elevator so that you can take your hands off the yoke, and the airplane continues with no change of altitude. That way you know that zero finger pressure on the yoke = level flight.
Best of luck with the rest..
