This looks good, but for an advanced novice you likely can still DL twice a week. And you may actually need to in order to drive progress. For 2x/wk DL you can still practice the power cleans by having them be part of the warm-up of one of your DL days (i.e., the lighter/volume day, for example).
Yes, you can substitute GMs or SLDL when you get to that stage.
