There should be absolutely no need to bleed the brakes if you didn't crack any lines. If you took the brake lines off, the yes. If you (for some reason) messed with the lines up by the brake booster under the hood, then yes. If you turned the bleed screws on the calipers, then yes.
If all you did was use a C-clamp to squeeze the pistons back to clear the new (thicker) pads to fit, then you shouldn't need to bleed.
When the vehicle is restarted the brakes may go to the floor initially, idling will get the pressure back from the boost pump. Also be sure to "bed" the new pads to the rotors by driving from about 60 MPH, then firmly but steadily (without activating ABS) slow down to about 40 MPH without coming to a complete stop (probably highway).
Do that a few times (6-7) then drive around a bit to cool them off, and all should be well.
Good Luck.
