Help with rooting!

I have quite the issue with the phone, i can't flash anything with Odin.

Here's what I did that got me into this mess and hopefully you guys can dig me out of this hole.
The phone was running 4.3, I rooted it using Kingo, then flashed CWM Recovery. When I attempted to reboot it it gave me a screen saying "System software not authorized by Verizon Wireless has been found on your phone..." So, I went into the recovery, opened Odin and tried to flash stock.vzw_root66.tar and got this:

Code:

So is my phone toast or can I fix this, im still a rooting noob, this is only my third phone ive messed with. :eek:

Edit: if i reboot the phone after being in the recovery i get "Firmware upgrade encountered an issue. Please use Software Repair Assistant & try again"
