cisco spanning tree, vlans and trunking

Just want to double check...

In a cluster of cisco 3550's, we have all the vlans trunked thru Gi ports (fiber, if it matters).  We use 801q.  If we turn off spanning tree, that should not affect the vlans or the trunking, correct?

    you are correct.

    Spanning tree just helps the switch determine witch path to take to reach a device.  Turning off spanning tree MAY affect the performance and/or routes, but it will not affect which VLAN the port is on or if you have configured the port for trunking.
