You could try a bottle of Techron Fuel System additive that specifically mentions that it conditions the fuel level sensor. I've heard it's pretty successful at fixing several of the common GM fuel level sensor issues.

A P0461 is a code for a "noisy" fuel level sensor. That is, the value changes much more rapidly and frequently than the PCM has calculated it should.

I am gonna try some of the Fuel Additive, last night i went out and messed with it after researching a little more and removed and reapplied the fuel cap and then unhooked the battery to see if it would reset, i fired it up and the light went out. I will see if it stays out when i drive to work tomorrow or not and go from there! Thank You for the suggestions so far.

It may take multiple drive cycles for the MIL to come back on. Give it days before declaring victory.
Disconnecting the battery resets the computer to factory defaults. The MIL is supposed to go out when this is done.
