For part b, how are you able to tell that BF3 is a Lewis acid? Where would the newly accepted electrons go on the Lewis structure? Would the new bond be formed with boron or with fluorine?

BF3 is a Lewis acid because Boron has an empty p-orbital. This means that it can accept an electron pair, which by definition is a Lewis acid. The new bond would be formed with the Boron.
