If I missed it I apologize , curious what tent, sleeping bag and pad you used?  Love this thread! 
Thermarest pad.  I would do this slightly different if I had a choice.  The air blowup type is the best as you are on top of rocks on top of ice.  It helps to even out the rocks from sticking in your back.
I got a kelty backcountry bed for this hunt.  It is rated down to about 20 degrees...but I got cold when it got below 40 degrees.  I would buy a warmer or different bag.
The guide had the tent and it was awesome.  With the constant downpours all night, mine would have surely leaked.  It was a Hilleberg and I don't care the weight.  This is bombproof and will keep you dry no matter the conditions.   It's on my list of things to buy.
