Recommendations for installing SP2 - probably the same for rollup packs :-

# We recommend that you upgrade your servers that are running the Mailbox server role after you upgrade your servers that are running the Client Access, Unified Messaging, Hub Transport, or Edge Transport server roles. Upgrade your computers in the following order:

   1. Client Access servers

   2. Unified Messaging servers

   3. Hub Transport servers

   4. Edge Transport servers

   5. Mailbox servers

If you upgrade your servers in this order, you may avoid potential service interruptions.

# We recommend that you upgrade Client Access servers that reside in Internet-facing sites before you upgrade Client Access servers that reside in sites without Internet connectivity.

Release notes for SP3 - please note the unsupported scenarios with 2008R2

Note that Microsoft only recommend applying Rollups if you are actually experiencing issues which the patch specifically fixes. It is always better in any other case to wait for next fully tested SP.
