Worked that way for me.
When I did a fresh install of Win7, all I did was update the firmware, turn on AHCI in BIOS, install the OS, and I was done. The install process was smart enough to turn off defrag and the other things not necessary for a SSD.
I did do a few tweaks afterward, but it was geared toward saving space rather than optimizing the SSD. My last system's C: drive was always on the ragged edge in terms of free disc space, and it caused me no end of problems. Made me a bit paranoid about space on the C: drive. So, for my new system, the tweaks included things like leaving pagefile on, but knocking down the space it uses to 512K, moving the "My Folders" space to a HDD, and moving cache, temp and other such folders from the application to the spindle based drive.
