Oil will be standard Castrol 0W-40 Euro and a Mann Filter.
Now to wait for parts! I haven't done this in a while...

15/85 is pretty low especially for VA. You guys get some cold temps. I'm somewhere around 40/60 + Water Wetter in TX, factory fill is 50/50. My car is also garaged - is yours? If left outside I would NOT do 15/85.
Also, antifreeze acts as a lubricant for the cooling system. I don't know if 15/85 is enough for the water pump and those things fail enough as it is.
Good luck on the OFHG! I just ordered that, valve cover gasket, eccentric shaft sensor, and a few other parts... have a long weekend ahead of me as well.
