Fire rings have a grove cut in the head and block. The fire ring is cut out of the stock head gasket, and another one is set in the two groves. Fire rings unless done perfectly don't like heat cycles. O-rings can be installed in the head, the block, or both. A groove is cut and a stainless wire is installed. The factory headgasket is run with o-rings. O-rings are better suited for street use, and will be all you will ever need.

Yeah, you can. You put the head on first, and then thread the studs in, just like you would do with the bolts.
