If you are coming up for flowers, I would highly suggest delaying your trip to the last week of July, if at all possible. The second week of July is too early for peak flowers on any other year. Perhaps even more so with all the snow around here this year. Time will tell.
You can drive to the Bells for free before 7 AM. Between 7 and 9 AM, there is a $10 fee. After 9 AM, you would have to take the bus. Obviously, you want the free option since that covers sunrise.
Crested Butte area is decent for flowers, but I would suggest skipping this area and heading straight to the San Juans if you want flowers. You'll have world's more flowers to choose from all in a central area. If your dates are set for the second week of July, though, your flowers will be very slim.
Finally, check out
Jack Brauer's site for a picture of Monday's sunrise above Yankee Boy. Not exactly spring-like conditions. More like mid-winter. You'll want more days between now and your trip.
