Dean, none of the Chicago Basin 14-ers are technical in August-Sept.(but I've not done N. Eolus, so I'm not sure about that one). If you will be going in Mid-July, a rope and axe might come in handy, in case of any snow issues. Usually, Windom and Sunlight are done together, starting with Windom, doing the connecting col, then descending back down into the basin from Sunlight. Eolus is an obvious trudge directly up from the basin.
The "standard" Bells 4 pass loop starts at the Maroon-Snowmass trailhead. You follow East Snowmass Creek south, then climb to Willow Pass. On past Crater Lake and south to West Maroon Pass. Northwest to Frigid Air Pass and then further NW to Geneva Lake. The back east on the Geneva Lake trail, over Trail Rider Pass, and down Snowmass Creek to the trailhead. But there are all sorts of other ways to do a loop in this area--your map will tell you how. Pick up a Trails Illustrated map for Maroon Bells-Redstone/Marble. I hate those maps, but they do provide a good overview.
Hope this helps.
