I always encourage people to learn all they can about the animals they wish to raise before ordering. You put the cart before the horse, so you have less than two weeks to learn.
Ask questions but do not rely on everyone here to teach you everything you need to know, which is a whole lot more than the few items you mentioned. There are too many variables and too many differing opinions for us to give you the education that you need. You need to find paths to information that you can read and decide if it applies to your situation.
Read everything you can, as birdlover suggested, including the link to caring for your chicks. You have to know how to prepare for and what to do on the day they arrive. If the post office calls to say they've arrived, its too late to start learning, because that is the day they either start growing or start dying.
If you are unaware of the usual problems that can develop in new chicks (and something often does,) then coming back to this thread to ask about it may be too late. I'm not saying you need to get a veterinary degree before the chicks arrive, but being aware of some of the usual problems and being prepared for them can often save some of their little lives. You should know where to find information that you need at the drop of a hat. (Posting a problem and waiting for someone to read it and reply is no substitute for being forwarned and prepared.)
Be prepared to move them into proper housing when they arrive. A cardboard box in the kitchen will work for a week or so but after that, a proper brooder will be necessary, followed by a proper (and secure) coop. (And, if you wish information that is relevant to your situation, you need to give some clue as to what part of the country you live in.)
Again, you need to take the responsibility for learning and raising the chicks. You have 33 little lives that will depend on you to know how to care for them. Ask questions here, but this thread should not be the alternative to seeking out the information you need.
Best of luck.
