Teri,
I assume you know that PSFT does not support SSE. To find such doco, you will probably have to go to something pre-SP22 (the release they dropped it's support) if you expect to see anything that might refer to an SSE installation.
I have an SP20 install guide, but basically, it just refers to SSE in parenthesis as it refers to AE. In other words, it seems to suggest the install is no different and where it is different, figure it out. But I didn't dig into the doc too deep. Let me know if you want me to send it to you.
