Welcome. Obviously you know not to make too great a jump in weight. What jumps did you make on the squat? What exactly was the "hurt"? Was it a stretched or pulled muscle or something more serious?
If your time is rushed you may want to consider a four day routine. I would consult a Starting Strength before switching to that. If you can do the program as written at least during the novice stage it's always better.
Your squat is about an 1" or so too deep which is not what usually happens to new people. Have a SS coach check it if not in person, which is always best, but online if not.
You body weight is a bit slight for your height but again, if you do the program as written and eat as suggested you will gain some weight as you gain strength.
