Go into the OEM messaging app and disable all notifications.
I found out neither GO SMS or Handcent will allow the text to call motion feature. I'm using the OEM app as I'd rather have the cool motion feature rather than slick looking texts

The motion feature is when you are in a text message (only in the stock messaging app), if you hold your phone up to your ear, it will call the person you were texting.
