Here it is cold and hard...
Pretty simple fix. Have a frame shop check it out, it'll may need a pull to align the horns. Maybe not, the front bumper assembly is mounted with four bolts, and it may have taken all the damage. It looks like you are going to need a front bumper cover, inside bumper support, possibly a front piece that welds on to the front "horns" and mounts the inside bumper support. Possibly one or both hinges. possibly some inner panels and brackets. The hood looks fixable. If it gets "totaled", salvage title almost no exceptions, and as far as a buy back, that's up to the insurance company....some do, some don't. If you want to keep the car insist on getting it fixed and don't mention totaling. If you want out, it should be fairly easy to get it totaled....most companies don't want the headaches of dealing with classic cars (or their owners). New replacement parts are almost impossible to obtain....although it is used parts that were damaged (think about it) If you can document all your recent improvements you will probably get reimbursed. In todays market, and 80k miles, a salvage title would drop the value of your car about 40%. Damage history vs no damage history maybe 10% at that mileage. Sorry for your loss, I know you put a lot of yourself into that car.
