Clever planning Jim. Really like the e-mail links with the daily maps idea. You two have the experience to make this work so I couldn't imagine adding anything of benefit other than a big thumbs up
I do recall it taking a seemingly long time to get up to Crater Lake and then back down. With gear on the bikes you won't likely be able to do more than enjoy the various pull-outs and lake overlooks from the caldera rim so a few hours actually above the lake seems like you are budgeting plenty of time.
