    First you need to start by figuring out how much amperage you need. That's the critical part. For example, what is the current draw of the air compressor?

    Second, I would suggest that if the outlets are going to be grouped near each other, you go with a GFCI breaker.

    Third I would suggest you read up on the requirements for outdoor receptacles in your area.

    Since it's an outdoor location, I'd suggest the GFCI outlet so the reset is nearby.

    The install MIGHT warrant a sub-panel.

    Whay you really need to do is determine:

    The 120 V tools you plan to run at the same time for the outlets. A typical circuit is 20 amps or 20*120 watts. Somethimes the GFCI outlet can only handle 15A and oulets below that can handle 20 Amps.

    The voltage and VA and.or HPof the compressor.

    Sometimes it's nice to put lighting on a separate circuit with at least two fixtures. If a bulb blows and your using a saw, your not left in the dark.

    If you overload a circuit, then your not left in the dark.

    Opinions can be changes based on your answers.
