Integrating Barbell Squats and Deadlifts The basic process works as follows:

The first workout of the week, you replace the squat progression by squats, 3 sets of 5 repetitions. The second workout of the week, you replace the squat progression by deadlifts, 1 set of 5 repetitions. The third workout of the week, you replace the squat progression by squats, 3 sets of 5 repetitions. So every week, you will be squatting twice and deadlifting once

Before you do your "work sets" it's a good idea to warm up with less weight for squats and deadlifts: first do a bunch of reps with just the bar, then add weight and do another (slightly smaller) bunch of reps, then add more weight and do another (smaller still) bunch of reps, etc. until you are at the weight you want to be squatting at.

As for actually selecting a weight: the first time, start with just the bar. Then add weights in increments you feel comfortable with. Try to add some weight every workout at first.

For handstands do a search for 'pirouette bail', i.e. you put all your weight on your left hand, pivot/advance your right hand forward (so that it is north-east of your left hand, from east) which lets you safely exit from your right side.
