This past summer my girlfriend and I hiked the ICT from Featherville, ID (south of the Sawtooths), north to HWY 12. We had a great adventure and would be happy to answer any questions, general or specific, about trail conditions, resupply ect... The main takeway is that this trail is really more of a route; not at all similar to the PCT in that you'll actually be in the wilds alone and that signage and maintenance are sparse. We did about 12 miles/day and that was certainly tough enough in the jungle gym of the ICT. For naviagtion we used the ICT maps from the Idaho parks site, a compass, and a keen Sacajawea intuition.
