Studying carefully

Hello Rabbi
In order for the study by ear to be more organized and consistent, is it necessary to first learn all the rules and concepts such as Torah and Rabbinic Law, Migo, Te’ma D’Kara, and all sorts of other things like the above, or can it be done simultaneously with the study by ear?
I ask this because I feel that during the course of my study, many questions and doubts arise, which in many cases are related to the same rules I listed above, and therefore I have a dilemma about what to do because on the one hand, studying them can greatly focus me on the issue and reduce questions that stem mainly from a lack of understanding of these concepts, and on the other hand, studying all of these things can greatly hinder theoretical study, and this creates complete confusion for me regarding the method of study. I know that this is a somewhat general question, but I would love to know what the Rabbi thinks about this matter.
