Is it need install SP3 on both nodes of SQL Server 2005 cluster environment?
Do we need to restart SQL Server Agent or any SQL Server services after SP3 applied?

Applying service packs on a cluster is a bit of a pain.  You have to install it on the primary node first and restart the failover node after it's installed.  If it's an Active/Active cluster some people recommend you move both active instances to one server, then install the SP on that server.

We have Active/Passive cluster. We call Node A - Active and Node B - Passive.So I can
- Applying SP3 on Node A
- Failing over from Node A to Node B
- Reboot Node A
- Applying SP3 on Node B
- Failing over from Node B to Node A
- Reboot Node B
Please correct me if something wrong.

If you are Active/Passive then apply SP3 to Node A and follow the prompts.  You don't need to apply SP3 to Node B, it will happen automatically.  (That's described on the web)
