No need to do core exercises if you are doing the oly. lifts, they target the core big time. You say you want to gain 25 pounds of muscle, you could go on the GOMAD diet which is SS and drinking a gallon of 2%/whole milk a day, and be sure to get as much protein and good fats in as possible. Abs are all diet, stress, sleep, and just a little core work (which the oly. lifts cover) to make the abs bigger. The 42 box jump will come with doing the squats, deadlift, and cleans, also training some plyometrics would help. Muscle ups will come with training pull ups and going all the way up to your chest and dips. Dips and Pull ups will come with training... you guessed it, dips and pull ups (Front lever will also help with pull ups).
Bicep curls are pretty useless, in my experience, pull ups has created more definition in my biceps and have slimmed them down from bulky to lean muscle.
Isometric holds (planche, front lever, etc.) should go after the warm up but infront of the actual workout.
I'll close it with this, if it was me I would go here
