a negative (-) times -3 = a positive number, hence +3

Don't be afraid to rewrite things a bit. It will help you win the battle.
-2(x-4)-(8x-3)=2-(6x-1)
First parentheses
-2x + 8 - (8x-3) = 2 - (6x-1)
Next parentheses
-2x + 8 - 8x + 3 = 2 - (6x-1)
Last parentheses
-2x + 8 - 8x + 3 = 2 - 6x + 1
See how easy that is to follow, now that we have written the entire expression every step of the way?
Okay, now what?

so when I see -(8x_3) I distribute the - sign as a coefficient of -1

That is a reasonable understanding. It is the same on the last parentheses.

-2x+4-8x+3=2-6x+1
=>-10x+5=-6x+3
=>-4x=-2
=>x=2
