Gokyo Ri maybe is not interesting itself, it's a pure 'trekking' peak, but it does provide one of the best panoramic view on 8000+ giants in Nepal. It is easy to climb (well, more likely, to hike), but altitude should be taken into account.. Anyways, trek from Lukla will give you all acclimatization you need..
Well.. KalaPattar is a bit higher than it states here.. Main picture shows might and beautiful Pumori, while KP is shown in front of it. It's brown snowless small (relatively) peak.
