Glad to hear you got the touch response figured out. Yes, with some settings, you do have to wait a few seconds to see the value because the LCD display will display other information, such as the name of the function, before it cycles to displaying the value for that function.
When learning to play, the ability to just "feel" your way around the keyboard will come naturally. When I started learning to play, I learned the notes to all of the basic chords (major, minor, 7th, minor 7th, diminished, diminished 7th) in all keys. For learning where the keys are without using labels, a good trick that I used was just to remember that the white key immediately to the left of the cluster of two black keys is a "C", and the white key immediately to the left of the cluster of three black keys is an "F", other notes are in a repeating order from "A" to "G" (so that, for example, once you identify the "C", the white key just to the right is a "D", and the white key just to the right of that is an "E", and so on), and this is true for any octave on the keyboard.
Although I did not start with scales right away, it is a good practice to learn scales as well, as that is good finger exercise.
I also worked on learning music theory, so I could identify the key of a song by the number of sharps or flats in the key signature (the "Circle of Fifths"), as well as the construction of more complex chords.
