Dear fellows:
OK. That's my turn now: I really need some help with my repertory. Let me explain the situation in a few words.
I've been playing the piano for the last 15 years or so. Fortunately in some respects, but unfortunately to my piano history, I am a classical guitar player as well. My professional career is related to both, but centered on the later. However, now that I'm approaching my 30's I decide to resume my piano playing and push it to my very personal limits. To do so, I'm thinking about a plan of repertory and that's the point: I want your kind opinion about it. It's important to say that despite the fact that I did play repertory by these and other composers, some of it more difficult, I am not sattisfied with my own results, and I'm returning to play after a couple of years gap. Because of that, please consider that I'm ready to play the first group properly, and nothing else. Here's the list (I think that each group shall take a year):
Part 1: to get some fresh air
Bach: Prelude and fugue in C minor (WTC I)
Mozart: Sonata K 280
Chopin: Polonaise opus 26/1
Brahms: Klavierstücke opus 117
Debussy: Preludes 9 and 12 from book 1
Part 2: to warm up
Bach: Toccata 5 BWV 914
Beethoven: Sonata opus 2/1
Chopin: a set of the Preludes opus 28 (ca.10', including at least two challenging ones)
Brahms: Klavierstücke opus 118
Debussy: Children's Corner
Part 3: OK...

Bach: Another P & F (A minor from book 1 for instance)
Mozart: Sonata K 310
Chopin: Scherzo 2
Liszt: a set of the Anees de Pelerinage (no idea about what exactly)
Debussy: Preludes 10 (book 1), and 3 (book 2)
Part 4: (no comments available)
Bach: Sonata BWV 964
Beethoven: one of the Sonatas opus 31, or opus 81a, or opus 53...

Chopin: another major work (ballade or scherzo)
Brahms: Rhapsodies opus 79
Debussy: Estampes
Thanks in advance for any suggestions, considerations, corrections, alterations, comments of any kind. Best wishes!
