What is above the garage?
If it is "attic" or truss space, it might be good to give it some strength by installing 1/2 ply, that way, if someone steps on it won't break the paneling.
Another thought would be to insulate the space either for heat retention/rejection and or noise. It definitely moderates the garage interior temperature.
Run lighting wires now, ditto air lines or auxiliary circuits/outlets.
The illustrated bead board paneling goes up quickly and also needs a bit of strength behind it if you want to even think about storing stuff above.
A pneumatic finish nailer would be the tool of choice and you might consider a simple 1x2 or crown molding to hide any gaps around the ceiling/wall perimeter.
Prefinishing will save your shoulders and back a lot of grief.

good luck,
