Waterproof darkcoth with Velcro closure, good lens shade to protect from moisture as well as water. Sturdiest tripod and head you can realistically travel with. Mass and weight help. A good parka. Paine is an extremely popular park with accommodations. Won't be like up on the peaks and their horrific weather. I don 't know if my nephew's ole Rock & Ice magazine article is still online too: Twenty Days of Paine by Chris Breemer, an obvious pun for "pain".That will give you a clue about the weather.
