I actually wouldn't do low pulls or high pulls for that matter. Until your technique on the full lifts, these will make learning the proper timing of getting under the bar difficult.
First I would...
1) AVOID THE POWER VARIATIONS OF THE LIFTS. So no power snatch or power clean until your technique in the full lifts is super efficient. Getting under the bar efficiently is super important at that point in your career. And doing too much "power" lifts when your full lift technique is not yet efficient will make it hard to become super efficient. Only introduce the power variations when your full lifts are solid, constant and stable. And even then if your full lifts are less than 112% of your "power" variation, don't spend too much time on the "power" variations.
You can do lifts from blocks or paused lifts (pause below or above the knees then finish the lift for example) BUT catch them in a full squat.
2) Building a strong back and front squat is important. But using a form specific to the Olympic lifts is even more important. Focus on maintaining an upright posture when you squat, not leaning forward and avoiding rounding the upper back when front squatting. Only go up in weight if you can maintain proper form.
3) At the moment don't do pulls, but do deadlifts. Snatch and clean deadlifts. Again, the goal is not to max out, but to use the exact same positions as you would in a clean/snatch.
4) Do plenty of work to strengthen the shoulders and lats.
So basically your workouts should look like:
A. Snatch variation
B. Clean & jerk variation
C. Squat or front squat
D. Snatch of clean deadlift
E. Upper body pressing work
F. Lats/back bodybuilding work twice a week
