The main difference is that GPRS phone is much more intellectual.
And in case of analogue modem you have PPP connection with your provider,
but in case of GPRS modem you have PPP connection directly with the phone,
and it translates ppp into gprs connection by itself.

As for ppp configuration it is very similar except for special
AT command that sets settings of gprs connection.  It may look like:
AT&K3;+CGDCONT=1,"IP","internet.beeline.ru",0,0,0;+CGQREQ=1,0,0,3,0,0

Also dialed number is weird and depends on the phone, not gprs operator.
It may look like:
ATD*99*1#
