Changing 2008 R2 SQL Service Account & Agent on Cluster

I have a 2 node active/passive 2008 R2 cluster running on Server 2008 R2. I did not realize you can't just change the SQL Service and SQL Server Agent service startup accounts in the Services MMC. I did this a few days ago and am not having issues that are noticable except do see failed logins for the account to the master DB every 15 minutes.

So, I need to fix this and think I understand how to do it, just need verification or correction.

On the Active Node
Use SQL Server Configuration Manager and change the SQL Service acount to Local System, apply, then change back to the domain account and apply once more

For the SQL Server Agent do the same as above

I assume this will apply the security changes and not fail to the passive node before applying. Am I correct in my procedure?

You are correct that the startup service accounts need to be configured in the configuration manager.  Changing the startup account will require a restart of each of the services you are reconfiguring and will impact your active cluster member accordingly

I do not have to do this on the passive node as well though, is that correct? It already has the correct account credentials.

No, if the passive cluster is already running with the correct service account(s), there should be no  need to reset it.
