You can enable TRIM with TRIM Enabler.

TRIM works for all SSDs, however it is only officially supported and automatically functional with Apple installed drives.

As for whether you need TRIM or not, the likelihood is you won't. TRIM was designed for early drives that had terrible garbage collection, this is now not a huge issue with any of the current drives on the market. You may need it if you are doing many writes and rewrites every day (and large ones, at that).

I'd disable the sudden motion sensor for the SSD by entering the following into Terminal:

sl takes the most common use of Unix ls, to display the files in a directory compactly in multiple columns, and makes it substantially more useful.

sl groups files by purpose so you can mentally organize many files quickly; for instance, it collects HTML and PHP files together, as opposed to leaving them mixed up with supporting images, CSS, and JavaScript. sl points out interesting files, which include those that have been recently modified, read relatively recently, are relatively large, have warnings, or need to be checked in to or out of version control.

sl is also aesthetically pleasing due to attention to layout and filtering as well as limiting color and text annotations to salient information.
