If the distributor you have is an MSD, it sounds like it only has a magnetic pick-up in it and will require a box to work, so your HEI will have to stay for now.
There are several different vaccum advance units that GM has used over the years, each with it's own characteristics. Without knowing what you've got and how much vaccum your engine is making, it's hard to say if you should use it or not. You can remove the whole thing and just use the mechanical advance mechanism in the distributor if you don't want to play with the vaccum unit. However, if you are driving this thing on the street, the vaccum advance will help out the idle a bit and may make it more pleasant to drive. If you do want to run it, but don't want to keep changing units to find which one works the best, you can buy an adjustable unit and play with it until you get it right. As far as the re-curve, Mr. Gasket 929G should cover that and I would recommend the MSD HEI module #83645. The MSD module is nice because it incorporates a rev limiter which I would always recommend.
On to the cooling problem. A cooler thermostat may help a little, but I don't think it's your cure. There are a few things to look at before we start making changes. I see you've got an electric fan. Is it wired properly to pull air and are the blades oriented correctly? Is it thermostaically controlled or manually controlled? You're running a serpentine set-up with what looks like a short water pump. It seems like the pump, based on what I can see of the belt routing, is turning the same direction as the engine. I believe only the Corvette used the short pump and if the pump was meant for a serpentine system, it may be a reverse rotation pump. After making sure everything is turning in the right direction you can try a new radiator cap with a higher pressure rating that will raise the boiling point of the coolant some more, but will expose any weak points in your cooling system. In all honesty, in the end, I think a higher capacity radiator is in order. I don't think the stock 2 core is going to keep up no matter what you do.
