It seems like you're approaching this in the right way by asking questions and tweaking your gear to have better trim and buoyancy with second order thinking of how this can impact you in the long run. You see way too many people with terrible fundamentals and finning skills while being overweighted to oblivion from poor instructor practices.
DIR is a great framework for gear configuration which can help streamline your setup and eliminate failure points. I can't speak to the quality of the brand of your BCD, but it does seem like a more or less standard BPW system with "deluxe" features (buckles, padding, etc. all things that manufactures try to upsell to make you think you need them). My first BPW was very similar (thanks, XDeep) with all the buckles and padding. Quickly realized I hated all of it and much preferred just a single piece of webbing and no padding at all. I've seen buckles get broken with tanks dropping on them or small pieces of plastic getting broken rendering the buckle useless. I also find padding to be more limiting than just the webbing by itself. Maybe that's just me.
Regardless of all that, don't be afraid to experiment with your gear and try new things out. It may very well help with your weighting issues. But it is worth looking into the why behind the DIR configuration vs. giving into peer pressure. There are a ton of resources out there including the "manual" of DIR diving: Doing It Right: The Fundamentals of Better Diving. The book discusses weighting and how to have a "balanced rig" which is an important concept to understand as you progress into diving.

But I would still take it one step at a time
