First off, that is a great report, I am envious!!
Yes, the trail down to the falls can be busy this time of year but the , photo opps are quite good ( even with the shortage of snow/rain) of the falls are great, and the fishing for natives spectacular.
Shadow lake is a nice day hike, busy also , but then again what isn't in the sierras. Think about the trail to lake Ediza, iceberg, and to upper iceberg. At upper iceberg lake you can look down on Devils Postpile!! Might require a couple of nights.
Again, thank you for the great report and pics, keep them coming.
