Every little bit of security/obsfucation helps.  Security layers are 
like an onion.  Moving the default port of SSH is just another layer 
that will throw off a whole bunch of port scanners, and let them 
concentrate on easier target hosts. 

Just changing the SSH port probably removes 90% of the threats with 10% 
of the effort.
