damn jump looks nice, if that's 9'8 then ya definitely getting like 10'9-10'10 on there..
for sure man just start a journal and begin logging, that way we can come up with a program etc.. if you plan on getting to 155 for summer, diet & 'cardio' starts now.. you'll want to start that as soon as possible and get to that goal quicker. Being that you're 165 it will only be minor adjustments..
start a journal, log what your current diet is generally like etc.. i know your knee is still getting healthy, so honestly, to lean out a bit right now it's just cleaning up diet a bit and doing light cardio like walking, basketball dribbling, shooting around etc.. i don't know how intense you can go on that knee so..
peace man
