Out of these, Infinitys would be easiest to drive for your receiver (rated 93db efficiency and 8ohm), thou eventually you should consider updating it for newer model with pre-outs.
ac4l.com runs some very good deals on refurbished models.
I don't know if you could play for large parties (it all depends how loud and how many people), but if you start hearing clipping and distortion - turn the volume down right away or you will damage the speakers.
