Where should I shape my traffic

Long story short, I need to shape traffic at one of my mpls sites. Remote office, 12 users, 1.5M t1. Recent changes with our provider is causing issues with this site to suffer massive packet loss when the serial link is saturated. I've had the same qos setup on my CE router for a year and the link has seen occasional saturation for that long as well, never experienced this much packet loss until now. But I digress.

Should I:

a) Shape outbound on the switch trunk port to gateway
b) Shape inbound on gateway port from switch
c) Shape outbound on serial interface

Any suggestions are appreciated.

This is my qos policy. Class-default is what is getting dropped.
