Is it common for MPLS routers to decrement the TTL inside the packet for each hop within the MPLS network? I thought that the whole point of MPLS was the packet doesn't need to be looked into?

IME, no, the TTL usually isn't decremented. It is configurable, though, and is sometimes done for visibility and/or troubleshooting.
