SG300 in Layer 3 for routing over MetroE

I have a project I am working on that will require routing over a MetroE circuit to connect a few sites together back to HQ. Although, I know this can be accomplished several ways, I have come up with a solution that I think will work, but would like you all's input as to whether this is adequate and if my thoughts on how to properly "organize" the network are right.

I have been working with the SG300 line in Layer 3 mode and have not had any issues in a test setup I have here in the office. Basically my thought is to have a single VLAN/subnet allocated for each physical site. That will handle the basic interoffice connectivity etc. I also have a need to prioritize voice/video traffic throughout the entire network. My plan was to create an additional VLAN/subnet to house the teleconferencing equipment. Thats pretty much the jist of the setup. My only question is how to properly prioritize the voice/video VLAN. Once I get into the policy mapping area of the switches the options begin to get scarce and I'm not quite sure if I have the ganularity I need. I'm also curious if there is an "easier" or "better" way to accomplish what I need.

Any and all help, comments, etc. are apporeciated...

Hi Brent, this basic QoS is already performed on the tagged packets per 802.1p.

Thanks for the reply Tom. Can you expand on what you are saying here? So I need to leave QoS in basic mode and... ? A link to any material would be helpful as well. I grasp most of the concepts at play here, just tieing them together is where I'm somewhat at a loss...
