Jomo Kenyatta International is quite small. Remember to watch your bags and to try and get a cart for taking you luggage past the taxi people (there are hundreds, or at least it seems like hundreds). Remember if you decide to take a taxi that you can bargain for that as well into Nairobi. Take what ever they give you and go for about half. If they get too sticky on the price go to the next ten guys. Someone will do it for less, trust us. You will also need to pay the departure tax when you leave ($20) so have some cash handy on the way home.
