A secure erase operation is effectively like TRIM for the whole SSD, but a little more comprehensive. It can be worth doing, but whatever you do, avoid performing any operations on your SSD with software that might be intended only for mechanical hard drives.
I like using Parted Magic. It's a specialized Linux distro for working with all kinds of drives. http://partedmagic.com/
A point about terminology: the term "secure erase" can depend on your context. On software that is SSD-aware "secure erase" = TRIM the whole drive, more or less. But there are also "secure erase / wipe" tools intended only for mechanical hard drives. Never use these on your SSD
