Are there any specific configurations for SSD's on mac?
It sounds like you found this blog post. Looks like he changes hibernate to mode 0 (so it doesn't create a sleep image file), mounts the drive in noatime mode. 
A note on TRIM, if you have a sandforce controller in your SSD, like the OWC drives and many (most) of the OCZ drive, it's not recommended to enable TRIM. It can cause instability and these newer controllers are supposed to do  much better cleanup. Intel drives are supposed to benefit quite a bit from TRIM though.
