What do I need my alternator wire kit to include when putting in a 200A street alternator?

It's going into a '96 T-bird. I've got the 4-gauge wire, 1 post, and 1 connector. Is that all I need for the wire upgrad? Also is it recommended that I get a shutdown relay for it. There's a 50A fuse kit offered by Jeg's; is that strong enough for my application.
