Hi vin1069. 

Most aftermarket front disc brake conversion kits force you into using a 15" rim because of the size of their rotor. That said, the stock factory front disc brake set-up maintained the use of the stock 14" rims. So if you use OEM/OER parts, you can stay with the stock 14" rims. Your choice.

Nothing wrong with the wide oval tires. My personal preference would also to purchase the radial versions from Coker or whomever your tire distributor of choice is. Radials are a superior tire to the original bias ply design of the day. So unless I am going for 100 points in a points judged show, use whatever tire you want. Its your car and your wallet.
