what do you call a "mpls link"? Do you have an IP interface connecting to a MPLS network implemented by a provider or do you operate a MPLS network yourself?

In any case you might have a look at

1) Enterprise QoS Solution Reference Network Design Guide Version 3.3


2) Layer 3 MPLS VPN Enterprise Consumer Guide Version 2


3) Various design guides for Unified communications


Hope this helps!

Yes of course, if you route it over the same links. This is why I pointed you to the design guides, which will tell you how to prioritize voip over data to avoid quality issues.
