Agree with all that say waterproof gear is bug proof (but you may want to take some rubber bands to lock down the cuffs if they aren't elastic).
I live in Alaska, however, and highly recommend you bring a head net. They are worth their weight in gold, and will save you sanity. My preference is the Sea to Summit, because it's long (full neck coverage and tucks into your shirt) and it's black (easier to see through black netting than green or white). Comes with a little stuff sack which I recommend you use for storage (or use a zip lock) since netting has a tendency to attach itself to anything velcro and then it rips when you pull it away.
As for sleeping- nights in Alaska get cool. If you wear a hat to bed, as I do, just pull your hat down over your eyes.
