I've done the rap version and it's not all that charming. Oh, the rappel is fine, and the pitch out of the gully offers some entertainment, but the upper park is loose and gravelly, only go that way if it's getting dark and you aren't going to summit.
There's a swell two person bivy just after the hand traverse, about a pitch before the Gendarme. It's a good alternative to a notch bivy on the first day if you've got some day left.
Approach shoes might be fine late season, but boots would be better early. When I took my son up there for his first alpine climb, it was the traverse out of Goat Pass and the snow descent from the false summit shoulder that worried me on the climb. We had poor runouts and his cheesy goodwill boots were sloppy as hell, and there just wasn't much help I could provide aside from kicking steps.
If you really only lead 5.8 you might be happier bringing rock shoes rather than just climbing in your Trango's, you'll move faster and feel more secure on the ridge proper.
It's a fine outing, you'll have a great time.
