Okay that sounds good. However, before you start diving into the most difficult romantic concerti, I suggest you take a look into more simple concerto to get some concert playing experience. Just a few suggestions, I also strongly suggest that you play something in an ensemble or a duo first before doing some real piano concerto's. Anyway, as for the suggestions:
Beethoven, Piano Concerto Nos. 1 and 2
Chopin, Piano Concerto No. 1
And if you wanna do some ensemble playing first:
Beethoven, Sonatas for violin and piano Nos. 7 in C minor, 8 in G major and 10 in G major
Shostakovich, Piano Quintet in G minor.
Good luck!
