there are not many good beginner "etudes," at least in terms of being simultaneously musically interesting and pedagogically important. but there are plenty of good things for a beginner to play that aren't necessarily etudes and will still contribute to your technical development. I suggest you search the forum for a thread by bernhard called something like "beautiful music that is not hard to play."
I personally don't have much of a taste for the schumann you mentioned, but if you like it then go for it, the pieces are very straightforward and do sound like real music. you could certainly try some of the easier chopin preludes (eg #4, #6, #7), the bach anna magdalena notebook, or even a very select few of the beethoven sonata movements (such as the famed 1st mvt of the moonlight op 27 #2 or either op 49 #1 or #2).
good luck!
