Yea, I think you're all over the board, and mixing concepts.
Extract versus All Grain is one choice.
Brewing kits versus your own recipes is another choice.
BIAB versus false bottom is a third.
BIAB is just a mash technique. It should really be called "Mash In A Bag"
I weigh my base malt from a 50lb sack, and add speciality grains from a couple of smaller bags. I crush them in my mill. The only way to get more hands-on the process would be to hand-crank the mill. That's independent of how I mash the grain.
In the end, brew what you want to drink using whatever process works best for you.
