And I agree with going back to mikra after other learning, although the simple psak I got years ago from Lakewood is to learn all 3 parts (mikra/mishna/gemora) in such a way that you finish all together by 120, and Gemora is larger .. I was not old enough for kaballah, so not sure where that fits in.
But notice that your midrash does not mention gemora at all, sifra is not it. Tzarich iyun.
