Strong and abundant yet soft flood-lighting!
Table and chairs-wise you seem to be set.
Chips can wait a little bit, given that 99% of players are clueless and most likely won't appreciate high-end chips.
Cards-wise, you can't really go wrong with any major brand of fully plastic cards, to begin with. Your preferences may become apparent with time.
Food-wise, make sure to offer something that has no sauce or ketchup and crap, and doesn't need a knife, so players can eat standing at the break, holding the dish in one hand and the fork in the other.
If you host really regularly, it is reasonable to ask everybody to pay for their portion.
Again for regular hosting, offer coffee, water and rivers of soda and some symbolic quantity of booze (a bottle of whisky, or, say, two bottles of wine) and ask for specific brands or specific quantities of booze to be brought by the prospective consumers.
PS: Allow vaping!
Edit: if you don't know any trusted (and competent) person to have as dedicated, non-playing dealer, get a cheap (not necessarily the cheapest) Chinese auto-shuffling machine on a side table. One deck in play, one deck shuffled.
