Sounds like a pretty good plan to me but I would contact Jim Hegyi and see what he would advise on the Irr. to Eagle route. I took a little walk on the first 500 out of Irr. and was really glad I was not portaging it.

The paddle up the Talon and through Boomerang with be the payoff for finding your way to Eagle. The picture of my GPS mounting system at the start of the Creeks and Trails story on canoestories.com is on the way to the 375 portage to Dragon. As I recall those little ponds on the route are not as big as they appear on the map. Note how there are two ways to exit the pond preceding the portage. This is one of those places where a GPS's Topo map will let you know that you are in the right pond and the little crease in the grass is the stream you want to take.
