John,
 
As Barry said, you might want to consider the 1.8 kHz optional filter if  
you operate SSB in heavy QRM, such as a contest.  The other two optional  
filters, 300 and 600 Hz, are for CW and CW/RTTY, respectively.   The  20 kHz, 6 
kHz and 2.4 kHz filters are standard.

For ssb,  the dsp filtering will be sufficient 99% of the time.  If you're  
a
somewhat serious ssb contester, pop a 1.8Khz filter in - otherwise,  don't
bother.  Narrow roofing filters potentially help much more with  cw.
