Get Fel-Pro #MS 9193 B. That's a complete intake/exhaust manifold set, and included the gasket for the heat riser. The intake/exhaust gasket is 3 peices, 2 end peices and a center peice. As far as the port rings go, they're not 100% necessary, but they do make aligning the intake to the head alot easier. Unless they've been removed from your engine, you don't ned to replace them. just re-use the originals. I personally use Permatex High Tack part #80062 for the intake gaskets.
