What are the top ten jazz standards i should learn/ know if I want to learn how to be a better at jazz piano?

The best thing you can do is go hard on it. You'll want to start bathing your ears in jazz sounds now because there will never be a point when you've heard enough. So start now. A good place to start is Miles Davis. Look up his 60s quintet with Herbie, Ron, Tony, and Wayne. They've got a bunch of amazing albums (I'm not exactly sure how many), and this stuff is packed full of useful language. Also get in the habit of reading the liner notes. You'll want to get to know other material by each of the players on each disc you hear. At the same time as you do this, you need to work on basic chops/technique. Make sure you know all your scales (major, melodic minor, harmonic minor, diminished and whole tone are your basic ones). Learn the modes of the major scales and practice patterns through all of them. things like going up the scale in thirds, diatonic triads, diatonic 7ths etc. as well as any patterns that you may make up. You should isolate some common chord progressions. Find left hand chord voicings that work well and learn the progression in 12 keys using those voicings. Then apply the patterns in your right hand over top of the voicings playing the progressions. This should keep you busy for about 5 years! lol. Also you would benefit from a good teacher. where are you from? It's hard to know a good teacher when your at your stage of the game, so maybe you should find someone you admire and ask them who a good teacher would be. You can also read my blog at http://www.jasonbernsteinmusic.com and try perusing the database at http://www.jazzrepertoiredb.com oh ya...youtube is the best thing to happen to jazz since....well it's great.
