The dull grey color simply means that you can't de-select it. This is normal for the phones own number.
You didn't mention the setting of "Send as SMS". When sending texts to any system that doesn't support iMessage regular SMS texts are sent. If the setting is off, you must set it to ON.
Go into Settings->Messages and make sure that Send as SMS is turned on.iPhone 5, iOS 6, iPad '4' 64GB AT&T (2), iPad 2

SMS is a carrier feature. Contact the carrier to troubleshooting.
The "Send as SMS" has nothing to do with the ability to send SMS messages. It merely allows for iMessages that are having issues being delivered to revert to an SMS.

While it is true the the setting shouldn't be an issue in the OP's case it could be in two instances...one, if the number he is sending to was ever in the iMessage database and two if the message system is screwed up. Toggling the setting could fix it and is an easy test.
Another test is to turn the messaging system off. In that case all texts will go via SMS. If it works then the problem likely resides in the iMessage system.iPhone 5, iOS 6, iPad '4' 64GB AT&T (2), iPad 2
