If iIuse the gsm tool to send the AT commands manually, or if I echo them out in the connection script, it will get to a point where it just hangs. So, I hit CTRL+C to cancel it and run pppd again and it goes a little further. Eventually I can get past setting the APN, then when it tries to dial, it fails. I've tried both *99***1# and *99# to no avail (Tier level 3 support told me they use *99#).

Here is the peers script from my Zaurus, which uses T-Mobile GPRS via bluetooth.  I think it might help:

/dev/rfcomm0
115200
connect '/usr/sbin/chat -s -v ABORT "NO CARRIER" ABORT "NO DIALTONE" ABORT "BUSY" "" "ATZ" OK ATDT*99***2# CONNECT'
crtscts
noipdefault
modem
usepeerdns
defaultroute
connect-delay 6000
remotename GPRS
