Vaccinations - your kitten should have come with his vaccination certificate and it will tell you when the next one's due. they need boosters a couple of times as kittens and then it's yearly.
Registration - most councils don't require the registration until the pet is 6 months old.
Also check with the council website about any cat legislation - ours requires all cats to be locked up after sundown (to protect wildlife).
Check with the RSPCA / Vet about microchipping & desexing. Specially if it's a boy, get it desexed sooner rather than later to stop it spraying on your furniture. The RSPCA offers cheap desexing & very cheap microchipping ($15) - although our council also offers pet days where microchipping is $15 too.
Also my one suggestion. Don't let your kitten into your bedroom at night. Its so hard to teach them that they can't come in later down the line, and they do like playing on the bed at 3 in the morning. Yes, speaking from personal experience
Can you make an outside enclosed cat playground? Keeps your cat safe and keeps other critters safe from your cat.
I have seen some amazing ones built that allow access from the house and go around trees and through the garden. They don't necessarily have to be expensive, you just have to think a bit creatively.
