Layer 2 Qos Cisco NBAR

My organisation will soon be implementing video and voice over IP.
I have done some research on QOS and seem to have the layer aspect of it sorted out with CBWFQ and a priority LLQ queue.

My question is, The core of the network is made up off Cisco 3750 switches. Each subnet has a layer 3 SVI interface on the switch.

Can I apply the CBWFQ LLQ type configuration on the SVI's and If I did that would I need to worry about any layer 2 QOS configuration?

Also, any hints and suggestions if using layer 3 qos on the svi's is going about this the wrong way.

Also, do 3750 layer 3 switches have the NBAR feature?

Unfortunately there's no dice on the NBAR as the only Catalyst switches on record with NBAR are the Catalyst 6000 and 6500 series.

The Catalyst 3750-METRO and 3750X series have CBWFQ configuration capability, but not the Catalyst 3750G or Catalyst 3750E series.

As long as your criteria aren't too complicated, you can use the older-style priority queuing mechanism on the SVIs.
