It doesn't make a difference whether you have active/active or active/passive. You still need one for each node, one for the cluster, and one for each SQL Server instance, if I remember correctly.

Dont' forget heartbeats, which you usually want on a separate network.

We have a three part series on building a 2 node cluster that should help you: http://www.sqlservercentral.com/articles/Clustering/73994/
