tomorrow is my 1st day of gym need advice

I want to learn all the push skills and I know it’s best to only focus on a small number of them at a time. Right now I’m increasing my HSPU reps to then move onto harder variations as well as training planche. One arm handstand is on my radar as well but that would probably be too much at the same time. Progress is a bit slow doing my HSPU and planche so would it be better to master HSPU combos and variations (90 degree, fingertip etc) and then practice planche or is it fine to do both at the same time. (Some advice on how oahs could fit into as well would be appreciated)

Name this move?

For someone prioritizing planche, what would an actual week of training look like in your experience? Mainly interested in how you'd structure the planche work across the week, frequency, hard vs submaximal days, approximate sets/volume, and where you'd put full planche specific work like banded holds/attempts. An example week would be really helpful.

Right now my max hspu reps are at 3 but I want to improve to be able to do at least 5 reps with ease so that I can start working on harder variations and combos. How should I work towards getting higher reps? Should I do ctw reps during my sessions or gtg with them or are there any better suggestions?
