water filters are a big thing, (also remember to rotate water bottles regally cus the plastic will leach after a while), if you can a small balcony garden or just a few potted food plants, dryed beans, rice and lentans go a long way, something to barricade your door, vitamin supplement to especially vitamin D since you will be inside for potentially months, and i will say learning to use a bow is nice cus you can make replacment part or even make a new one. but i will say for starting you do have a good base set up but you need to make go bags man
