I have not studied all of your trip details, and cannot comment.
In September, even after a warm summer, you will see snow on many mountains. Glaciers have been receding over the recent years, but they are still there, every day of the year. Whether you can see them will depend on the weather. September is, to a modest degree, the best month for weather for viewing scenery.
It makes no difference which direction you travel on the lake boat on the Brienzersee (Lake Brienz.) Watch the boat schedules if you leave luggage at a train station. Luggage ofices are not open much after late aftrernoon. See below. The train and boat stations are very close to each other at Brienz. I recall a short walk at Interlaken, but it has been many years since I did it.
In addition to leaving your luggage at a hotel, you may leave it at almost all train stations.
The SBB website has information about each station.
Here is the listing for Interlaken Ost:
The left luggage office is open from 0700 until 1830 everyday.
At Brienz, the open hours vary by the day of the week:
