We are in process of upgrading from 6xT1 MLPPP going to Qwest too a fractional DS3. Does anyone have an example config of 36xx series router with a DS3 card configured for Internet connectivity they are willing to share?

Since you are getting a sub-rated DS3, the main thing is your DSU bandwidth. Without knowing how many channels you are getting I can't say. I see on your Sprint DS3 you've got full bandwidth (44210). You'll want to ask the provider what to set it to when you are turning it up. I would recommend enabling payload scrambling as well. Just use your Sprint connection as a guide:
interface Serial1/1 (or whatever) description Subrate DS3 to ; ; (maybe even the number to the help desk of your provider) ip address XXX.XXX.XXX.XXX 255.255.255.252 ip verify unicast reverse-path no ip redirects no ip unreachables no ip proxy-arp encapsulation ppp ip route-cache flow dsu bandwidth scramble
