No, seriously. What is the clustering system in use? 'cos the Symantec / Veritas cluster you'll need to go through the process on all servers individually, whereas (as I understand it), you may be able to only do one of the active servers in a MSCS environment. (You'll probably have to shut down the other active node temporarily...)
I have a clustering bloke here, and I'm trying to learn from him - when he's not too busy!

First of all, cluster administration is a tricky business - especially when running on anything before Windows 2008 and SQL 2008. Before doing anything: read, understand, practice, prepare (incl. backup), then implement.
I agree with Thomas that you have to be careful depending upon environment. As I understand it, you install the SP on the active node, and it takes care of the other nodes. I think you need to fail service over to one of the nodes after reading the information below.
As found in the SP3 Release Notes from Microsoft:
Installing SQL Server 2005 SP3 on a Failover Cluster Instance Note the following information before you install SP3 on a failover cluster instance:
For more information about failover cluster installation, see the "Installing the Service Pack (Hotfix)" topic in the SQL Server 2005 SP3 Setup documentation. The Setup documentation is available from the SQL Server 2005 SP3 Readme Files download page.
