There is a lot more you can do...
Research if any proprietary features make a difference to performance/lifespan and enable/disable as necessary.
Enabling AHCI and using your fastest available SATA ports have already been mentioned.
Maybe not something you want to to with a 120GB SSD but you can shrink or move your page file and disable system restore and enable regular backups to a storage drive using "Windows 7 File Recovery" in Windows 8 or "Backup & Restore" in Windows 7, you could save upto ≈35GB.
Disable Hibernate, normally frees up a GB or 2
Check TRIM is enabled, it would normally be on by default in Win 7 & 8. You can check in the command prompt. The TRIM feature physically clears deleted files from the flash instead of clearing the log so when new information needs to be written it won't have to format the flash in the process.
Disable indexing of the SSD if you don't have much of a use for it, this will prevent automated writes to your dive whenever file changes are made even in other drives. Avoiding defrag will also increase the lifespan, SSDs store data randomly and don't need to be defragmented.
Enable/disable write caching, this may or may not improve performance depending on how much DRAM cache you SSD has built in, download CrystalDiskMark and see how your SSD performs with it on and off. No install required just run the download from a folder.
Do not alter "Superfetch" or "Prefetch" process values in the registry, It has been discussed by Mark Russinovich and Ed Bott that it is a myth that won't enhance performance.
