My partner Larry and I did the N. Ridge on Sunday using a 60m half rope that we doubled up. Originally the idea was to just use it as a single strand but the rope drag was heinous and slowed us down considerably. So we doubled it and it made for really nice, comfy simulclimbing. We had none of the rope management problems that Fleb noted above. As a matter of fact, I would recommend this method.
I will second the recommendation for crampons on the traverse. Although not absolutely necessary if you're wearing heavy boots (I was wearing la sprotiva approach shoes) that you can kick steps in, you'll feel one hell of a lot more comfortable with crampons.
For a rack we brought 4 cams (green camelot, black metolius, purple metolius and #4 camalot), a rack of hexes and a rack of stoppers. We never used all of our gear. We were moving slow so bypassed the gendarme which in hindsight might have actually been faster.
Bugs weren't bad down by Ingalls Creek nor anywhere on the route. They were heinous at Longs Pass and the trail ascending it. Fuckers were divebombing my eyeballs.
