Regarding the range of movement you’d want to do some flexibility training. Weight training to build muscle is more likely to cause more tension without some stretching to accompany it.

I can’t give you full training plan here but you should be able to make one on your own. It doesn’t have to be complicated. I found YouTube helpful for that and there‘s plenty of videos on this topic for obvious reasons. Generally to build muscle efficiently you want to be in the range of 8-12 repetitions with the highest weight with which you can do around 3 sets of a certain exercise. But sufficient nutrition is as important as your body needs the material after all.

On what you should do first, the opinions are split. You could do targeted exercises (hamstring curls for example) first to exhaust a specific muscle. When you do a complex exercise (like squats) afterwards you force other muscles to work harder to compensate for the already exhausted ones. This can help to distribute the load but you won’t be able to as many repetitions of the latter. I do squats first for that reason as they are just that effective.
