What wireless transceiver should I use?

Im planning on adding a wireless system to my next bot but am totally new to the subject. Ive decided on two transceivers for 2way communcation from both ends but have no idea which ones to get. Here are three possible options im looking into. My question is how hard is it to connect these to a picaxe and a computer and which one would be best for a beginner.
