Yes!
> Is rotating your hips into the wall something you should do on the majority of holds? What about overhangs?
It's a handy 'trick', one that some people use a lot more than others. There are times it's near essential, times where it's an unnecessary flourish.

Best bet is to go play with the new ideas at the wall/crag. Figure out what works for you, what doesn't and importantly, what seems to work for others that you're not yet trying or are currently struggling with. Try the same easy ish problem as many different ways as you can think of, watch and ask others for ideas. Why does or doesn't something work? Can your new insight improve the sequence/move further?
Learning to read the holds, figure out the moves as you approach them takes quite a bit of work, there's usually a lot of options and subtlety possible. For every 'rule' there are plenty of exceptions, some will suit you* better than others, there is no 'right' or 'wrong' way
*'you' of course will gradually change as your experience and physique develop
Enjoy the process, make sure it's still all about having fun but a little time spent analysing what's actually happening as you climb is very valuable even if you initially get the analysis wrong or are a bit stumped. I often get stumped trying to figure out how some subtle shifts make an impossible move easy (and sometimes visa versa!) but the reflection process is still an important part of learning for me.
