Sounds like you are doing okay for a set up. You can always upgrade if you want later. At this point, the only thing you *really* need is a plan.
Are you going to be playing cash games or a tourney? If you are playing a tourney you will need a good blind structure and a timer. People here are good about helping with that sort of thing.
Chip racks are a useful tool if you don't have a case; probably better than bags.
If you are playing a cash game, I really recommend a banker. This is usually the host, but not always. Having only one person take money, give out chips, and cash people out at the end really circumvents any major F* ups at the end.
The other thing I would recommend to have on hand is some rules. If you are the host, familiarize yourself with them first. Robert's rules of poker are commonly used; here is a useful
printable version . Robert's rules covers tournaments, but if you want you can also check out the
Tournament Director's Association version.
If you are playing with two decks, it is useful to have both in play simultaneously. We usually have the person who dealt the hand shuffle the cards (clean up your mess!), then pass them on to the SB, who will deal next time.
