Yes sir...it works with servos unplugged!  Can I run a separate +9v to power the servos?

No, most servos are only rated for up to 5 or 6 volts. You will either need an external 5v power supply, or put a regulator (like a 7805) on the 9v supply to drop it down to 5 volts.

I powered up the servos with separate power from 4 AA's and it worked!  Man...I really appreciate your help.  In the back of my mind I was thinking maybe it was a power issue but thought "Nah..it's hooked up to the USB so it should have plenty of power for 2 servos and the Ping."  ...I sure was wrong!  Thank you so much...I've spent most of the day trying to debug my code.  Not necessarily a bad thing since giving it that much scrutiny helped me to understand it more.  

Oops...just read your reply about the extra voltage being a no-no.  Will have to figure out something to remedy that.  Glad I now know what the issue is!

4 aa cells are ok, thats around 6 volts. But most servos won't like much more than that
