As far as I know the 74ACT parts are undefined for logic levels when you run them off of 3.3V. That's not to say I haven't run them off 3.3. They don't seem to catch fire and explode...
I would only recomend them for a 5V powered design. I don't know if the driver IC + mini 5V regulator takes up less space than the FET drivers or not. A TO-92 78L05 would be plenty of current. They don't need much bypass to be stable.
