    It could be 15, 20 or 30 amp depending on what you need to feed.

    As far as spacing, there is none. You can put as many or as few receptacles as the owner wants.

    Probably a good idea to come out of the line side of your garage GFCI and hit the door opener receptacles. Some door openers don't like to be on GFCI's for reasons that are a bit unclear to me.

    I have wired an entire garage on one 20 amp circuit, including the GDO's (they were on the load side of the GFCI as well). I've never had a problem with the breaker tripping or the GFCI tripping, other than one time for an unknown reason.

    It's the "Excellerator" and similar garage door openers that have DC motors with some sort of DC drive in the opener that cause the problems with GFCI's. That's a small percentage of openers, but I'd rather not get caught with my pants down, when the GDO receptacles really don't need GFCI protection anyhow.

    I never put the DO on load side in case the GFI should trip, whether the fault of the DO or not, and HO does not come home to a non-functioning opener. As far as size and spacing of receptacles, 15a ccircuit is fine, as mentioned earlier, and all you need is one, as long as it is not single outlet for appliance. I do like to combine garage recept with outdoor recept to cut down on # of GFI and convenient location for outside GFI control. All that depends on distance and quantity of receptacles, though.

    Under the 2008 NEC I believe that option will disappear, if I recall correctly all 15 and 20 amp 125 volt garage receptacle will have to be GFCI protected.

    You are correct Sir......
    2008 NEC Code -
    (A) Dwelling Units. All 125-volt, single-phase, 15- and
    20-ampere receptacles installed in the locations specified in
    (1) through (8) shall have ground-fault circuit-interrupter
    protection for personnel.
    (1) Bathrooms
    (2) Garages, and also accessory buildings that have a floor
    located at or below grade level not intended as habitable
    rooms and limited to storage areas, work areas,
    and areas of similar use [ROP 2–50]
    [ROP 2–40, 2–41, 2–51]

    Below are the exceptions that were removed for 2008 cycle:

    Exception No. 1 to (2): Receptacles that are not readily
    accessible.
    Exception No. 2 to (2): A single receptacle or a duplex receptacle
    for two appliances located within dedicated space for
    each appliance that, in normal use, is not easily moved from
    one place to another and that is cord-and-plug connected in
    accordance with 400.7(A)(6), (A)(7), or (A)(8).
