Re: type of vapor barrier
Tyvek is not vapor barrier; it is intentionally a vapor-permeable water shield that goes on the cold side of the structure, generally under the siding/behind the brick veneer. You would ant 6-mil plastic sheeting, with all the seams taped. and caulked at the floor line, directly under the drywall or finish.
On the block walls, I would apply a waterproof sealer on the inside. Will you furr-out the block and drywall?
The thing most people never think of is taking advantage of the inherent thermal mass of concrete block walls to moderate the climate in the structure. If you think about it, you will see that on a block structure, you want the insulation on the outside, where once the block is brought up to temperature in the winter, it takes a small input of heat to keep that mass warm, if you have prevented loss from the outside. That's why it's called "out-sulating".

Remove not the ancient landmark, which your fathers have set.
