I have an a answer for No. 2

You can't fight the final final boss there, but you can kick Paragon's Butt as many times as you want. Just head back to the last cloister and he will be towards the back of the area.

Too be honest, Lvl 60 seems too low, Id say Late 70's higher. 80's are preferable, if you can, 90's.

Besides you'll level up some in the later cloisters.
