Anyone know what it means when a port on a 3550 alternates from green to orange? The port still works.

These might be due to collisions which might be caused by duplex mismatch
Do a show interface and take a look at the error count
Wait a few minutes and do a show interface again. Did the error count increase?

Yes they did.

By "orange", I take it you mean Cisco's "amber"... :-)
This is a link fault caused by an error affecting connectivity such as excessive collisions, CRC errors, and alignment and jabber errors - which the switch all monitors for link-fault indications. For more information see Table 1-7: Meaning of LED Colors in Different Modes on the Switch here http://www.cisco.com/en/US/products/hw/switches/ps646/products_installation_guide_chapter09186a008011b58c.html#18799.
The port will still let data through as you say, but you probably need to address the causes by debug/show output analyses. Here's some information on troubleshooting the 3550: http://www.cisco.com/en/US/products/hw/switches/ps646/products_installation_guide_chapter09186a00801ab959.html.
