I fed them with 125w monoblocks and they were very happy with that in a much larger room. I also drove them with my integrated amp, which is rated at a true 105w in a room a bit larger than that. Though on the less sensitive side, these guys don't need a ton of power. They can handle plenty though.
14 AWG wire will work for nearly all needs in a typical home setting.
For just the 2 speakers, he could look at the Emotiva BPA-1 amp for a very simple setup, unless he has multiple devices to feed it with (DVD, game system, etc...).
