Stick to the big 3 (S.B.DL) Keep them as a priority. At this point of just getting back into it, darn near anything should work. You know how to train, just modify your training as I previously suggested. That squat does need to be closer to your DL. If you are not using them and I hope you are, get a good set of knee wraps.
Now the best thing I can tell you is welcome back into the fold. Enjoy the time you can spend in the gym and don't over analyze anything at this point.
