Piano Forum

so a bit of (unnecessary) background:(feel free to skip over this part)
my school has an incredible music program and i am lucky enough to be part of their symphony orchestra. we are paying a visit to a school in san francisco from LA and as a result we need to do some fundraising.
so last year when we tried fundraising for our carnegie trip what worked best was what was known as "an evening of eclectic ensembles" which was held by our orchestra boosters. this was advertised by our teacher as an extra performing opportunity with our friends because the program of the concert is composed entirely of willing chamber groups from the orchestra who played anything they wanted within a time limit. around 10-15 dollars got you dinner and entrance to the building where the program was held
i don't really have any good friends so i didn't do the program last year. this year i want to perform something and since i already play the violin in class, i figured that i would do something with the piano. i didn't want to do any accompaniments for soloists because as previously stated, that was too personal and i had no good friends.
so i decided on a movement of a piano concerto. i figured that this would be refreshing and impressive(i like performing and having the attention). beethoven was my favorite composer by a long shot and there was a 6 minute limit so the only piano concerto movement by him was no.2 mvt.3. i decided to give it a go despite the difficulty of organizing such a movement from just my high school peers.

now for the important info(for me at least)
our orchestra director stays out of these groups as they are usually chamber groups. so that means we will not have him as a conductor for this.
i have 2 months to learn the piece and put it together with the rest of the orchestra, the evening is on march 10th.

so the question is:
am i ready for this piece?
i am currently working on beethoven op. 81a. i got the 1st and 2nd movement down but am having trouble with some of the runs in the third movement. as far as my technique goes i can play waldstein 1+2 comfortably as well as appasionata 2+3(slight trouble with the coda though). musicality and expression is a whole nother topic lol
what are the hardest parts of this piece? i looked at the music and the only thing that really stands out are the minor third trills. they look monstrous, especially at that tempo.
the only previous chamber experience i have had with piano was with beethoven op.6 for four hands, but i am sure that this is at a completely new level of playing and communication(expeciallu without a director)
thanks!
