Also, keep in mind that I am more about training techniques than fitness. So, the % of fat to muscle doesn't phase me. I'm more about running three miles without tax, doing handstands for periods of time, and confidently completing multiple techniques and flips (practical).
a couple things to add: your goals are very technique oriented (which is fine) but it would help to have some sort of strength goals as well. if you're stronger you will be able to jump higher/farther/with more control, pull yourself up faster/easier/etc. Just by becoming stronger and more explosive you can improve all of your techniques.
You would probably want to look into starting strength or similar programs like Bill Starr's 3x5 for beginners (google these; tons of resources on them). As a new trainee the gains will come very quick so long as you learn proper form and are consistent. If you didn't want to try these programs (which would mean missing out on a fast route to an intermediate level of strength) then you could at least pick out a few exercises, say 1 push, pull, legs, and core to zone in on. For example: dips, pull ups, squat, and L-sit. Then you just focus on linear progression and add weight/decrease leverage to make them a little harder each session, sticking to 3x4-6 reps after a warm up. It'd also be best to focus on strength first, since greater strength increases your potential endurance, whereas endurance doesn't carryover into strength.
also, although you may say, "i want a higher wall run" that is quite vague. That could mean just 1 inch higher (which growing could take care of) or a whole foot. A wall run is not the easiest thing to use as a reference point for your training, whereas if you were too look at your vertical leap/box jump you can more accurately gauge progress, and there is still a large carryover to your wall run. A vertical leap is not nearly so technique focused, and can still accurately represent your explosiveness.
