That is a good starter set from NB. I think its best to start out with 2 carboys.
I bought my starter kit from Midwest, they are a little cheaper.

It comes with 2 glass carboys, but for $20 less you can get 2 better bottles. I prefer glass.
The only other thing you need is a big pot. If you are doing all grain, I suggest getting a turkey fryer setup. If you are going to do extract on the stove, get a pot that is big enough to hold 2-3 gallons.
