Good luck to you and I think you are on the right track.
When I started shaving the norm was people had 1 razor, 1 soap/cream and used whatever blades were available when they ran out. You used what you had and figured out how to make it work. I still think that is a good strategy for beginners to use. Get the basics of shaving and lathering down pat first before adding variables by changing things in your routine. When you do change things only change one at a time so you will know if that is what really helped your shave.
Personally I have gone from changing everything around daily to trying to use the same brush, soap/cream and AS for a week at a time. I use a different razor daily just to some variety in there. That has really helped me get to know the soaps/creams and brushes that I have much better, which has lead to better more consistent lathering and that in turn has lead to better shaves.
You get to know your shaving gear like an old friend instead of like a passing acquaintance. It really can make a difference.
