My concern is that I do not want more than 1 instance of the services being started up.

I don't get it. Cluster services are usually there for this kind of
thing: making sure a service runs only once, or that no more than x
instances are running... But now you want that king of control for the
cluster services itself.. Are you trying to build a cluster of clusters???

I have no experience of RedHat cluster but I did use LinuxHA, and you
would run the cluster software on every nodes no matter if the clustered
services will be running there or no. Maybe your cluster is not properly
configured...
