I would use degreaser to knock all the debris off then, use brake clean or a cleaner like inhibosol or Carb cleaner. Then I used Dupont Hi-Temp Engine Paint with ceramic it holds up very well and is resistant to anti-freeze and oil and some other chemicals.
If your stock pan is in good shape then just put a new gasket on that or get the 7qt it wouldn't hurt. I like my 7qt Canton, but oil changes can get expensive

if you run synthetic.
