A month is fine - you won't (or shouldn't) have any issues. The longest I have left mine is 6 weeks....
Simple dos and don'ts:
Don't just start the engine and let it idle for a bit; it's bad for most cars, not just a 300zx - if you start it, drive it straight away
If it's locked in the garage, don't arm your alarm! This will drain the battery over a month - if you have a cat-1 system the immobiliser will be active anyway.
You could disconnect the battery - I never bother as I don't want to keep programming my radio - and if the battery is in good condition it should be fine connected.
But you can always invest in a Ring Ultra Boost jump starter, just in case.
