Help to verify my setup at work with MLAG's and LACP.

I'd like to get some verification on what I'm planning on doing at my work. I'm a lone IT guy in a local office of a larger company that like to leave us to our own devices. :) Before I go much farther I'd like to make sure my though process is correct.

This is what I'm planning on doing:

I currently have a couple HP 2920 switches stacked into a single unit. All my server connections currently connect directly and only at 1G. I want to pikcup a couple of the FS.com S5800-8TF12S switches and mount them in the rack for 10G connectivity for my servers.

So in the end the two FS.com switches would be paired together in an MLAG (they don't support stacking) setup, in the back of one of the 2920's I have a SFP+ card, so a 10G connection to each FS.com switch, and then on the other side, each server will get a dual port card for 10G connections to each FS.com switch.

I realize this gets me good redundancy, but not sure if this makes sense, or gets me anything speed wise.

Do I setup a LACP trunk on the 2920 to each FS.com switch, do I use NIC Teaming on the servers to the switches? Or is this all just a terrible idea? :) I want to get a handle on the right direction to go.
