Welcome back to the addiction! Well those are definitely two of the main things you need. Filter, Water conditioner such as prime, liquid water test kit, gravel vac, substrate, silk or real plants, a cave or two. Are you doing fish IN or fish LESS? If fish LESS then you need pure ammonia or a raw shrimp or something else as an ammonia source. Do you have an in tank thermometer? A quality food such as Omega One or New Life Spectrum pellets. Ummmmm, that's all I can think of right now. Good luck & ask more questions if need be.
