We are pleased to announce that ArcGIS 9.3.1 Service Pack 2 was released today. We recommend that all ArcGIS 9.3.1 users download and install Service Pack 2 at their earliest convenience, to ensure the highest quality experience when working with ArcGIS 9.3.1.
With Service Pack 2 now available, there is an accompanying list of the issues that were addressed within the new service pack. These issues are listed in the links below under the "Issues Addressed" section. Many of these issues came directly from customers reporting them to Esri Support Services and were prioritized to be included in this service pack.
For details on each individual product’s service pack, the issues addressed, instructions on how to install the service pack and other information, see each product’s link below:
If you run into any issues with the installation of this service pack or have any feedback, please contact Esri Technical Support at 1-888-377-4575 option 2. International sites, please contact your local Esri software distributor.

"Service Pack 2 is cumulative and contains the fixes from all previous 9.3.1 patches. If you have a previous patch installed, you may apply Service Pack 2 over it to update the required files."
A better question, is whether the patch for image catalogs is required with this service pack, if it wasn't installed due to not using SP1.
"ArcGIS Image Server 9.3.1 or 9.3.1 Service Pack 1 must be installed before you can install Service Pack 2. Service Pack 2 is cumulative and contains the fixes from all previous 9.3.1 patches and Service Packs."
