The MacRumors Community doesn't know why Apple added this into System Profiler. If I remember correctly it was added with 10.6.3.
 
You will have to do a complete erase of your SSD from time to time to restore performance and compensate for OSX's lack of TRIM. You can do that by using GParted CD and following instructions on "ATA Secure Erase" on a Wiki page (google it).

Not necessary with the Intel G2 drives. They don't loose performance.
You can do it once in a year if it makes you happy, but it's a lot of hassle for regaining a few percent (less than 5).

Not really no. Though OS X lacks TRIM, have yet to hear of a case of major SSD speed degradation in OS X (slashdot even did a test a not to long ago showing that speed degradation is very limited in OS X despite its lack of TRIM).
