You can generally ignore U codes clear them and see if they come back.

I don't understand your logic it's not just to get threw an mot is it. Your selling it to someone so why risk their saftey on part worn tyres. Man up buy new !! If I was the buyer and found out you were fitting part warns I would walk away from the purchase.

Engines are like a box of chocolates.......

It's better than the tdv6 because it's a v8 so you don't worry about crank issues Apart from that there the same car with the same other issues

No idea but a mate was just charged over £500 for changing a water pump genuin pump mined £153.27 for parts rest was labour think it takes me an hour or 2 for a water pump. If your gonna pay someone for a head gasket expect 1500 to 2000 minimum and that's if nothing else breaks while they do it
