1 yes. The more low freqencies you pump into such a tiny room, the more you will suffer from room modes, and all the more so if the room is square.
2 irrespective of price, the best speakers that I know for such a small room would be the Harbeth P3ESR. They are perfectly neutral, with a mid range to die for. All they lack is low frequency extension, but in your case that is an advantage. Since it is a sealed system, they can be placed relatively close to the rear wall.
