Mine is 32x80 (the door) and is warp, is a 34x82 prehung the one needed to it?

You order/buy the door by the door size, not the rough opening. So you would buy a 32x80 door.
You will also need to know the jamb width; it varies depending on wall thickness and construction, especially for exterior doors (which door from house to garage usually counts as). For a garage to home entry door, you usually cannot have glass, it needs a 20 minute fire rating, and it needs a closer. (That is typical; local codes may vary.) Those requirements usually lead to a steel door.

Good luck with your project.

Some online sources may list the size of the brickmould (the exterior trim) in addition to the actual door size. A 32 x 80 door would have an outside brickmould dimension of roughly 36 x 83.

But Paul is correct, the prehung door you buy should say it is 32x80.

To expand a little on my earlier post...you really should remove the interior trim and double check the rough opening size. Usually it's 2 inches wider and taller than the door, but I've seen some that were less than that and that can cause problems with prehung doors, especially if the opening isn't perfectly square. The door manufacturer usually provides overall dimensions of the frame and also the overall dimension of the brick mold as X mentioned. It's a good idea to verify all of these to avoid surprises.
