This is a great chance to clean up all of those annoying bugs and errors that you have in your SharePoint deployment.

You can get the packs here:

• SP2 for WSS v3
• SP2 for MOSS 2007

What’s really important is that this is a great chance for you to work some bugs out of your SharePoint deployment. SP2 combines all of the previous CU cumulative patches and adds improvement to:

• performance
• reliability
• search and crawling
• alternative browser support

Don’t forget to do regression testing with any existing custom code or 3rd party solutions before you commit to deploying into production.  Plan a relatively large maintenance window because you must deploy the pack for WSS first and then MOSS and each time you must run them in succession one after another.  For more direction on deploying SharePoint updates, see the TechNet article here.  Although it’s not updated quite yet, there will be more information about it posted soon on the "Updates Resource Center for SharePoint Products and Technologies" also found on TechNet.  And, as you might have guessed, Joel Oleson has a very useful and comprehensive post about the goodies that are baked into SP2.
