Hi Guish! Here are some answers:
1) No, such print at home passes don't require any further activation. Your names and travel dates should be printed on them, so you're ready to travel right after landing.
2) The Trümmelbach falls are kind of in between Lauterbrunnen and Stechelberg, so both descents (either using the cable car between Mürren and Stechelberg, or the cog train to Grütschalp and the cable car down to Lauterbrunnen) will be fine. From both Lauterbrunnen and Stechelberg, buses will get you to the falls. Enter "Trümmelbachfälle" as you destination in the timetable to find all options.
3) Yes, you'll easily manage to visit Lauterbrunnen too.
4) Our personal tips are listed at our Lucerne page.
I think your plans for June 29 are fine. I'm not that sure about June 30. Are you actually planning to spend the night in Bern? If so, it's quite a long day trip to visit both Lausanne and Montreux. It can certainly be done, but focusing on the Bernese Oberland is another option. It all depends on what you and your travel party like to visit most, and what amount of traveling is acceptable to you.
As for July 1: Lake Basel doesn't exist. Did you mean Lake Brienz instead? If Lake Thun and Lake Brienz are your desinations, Bern isn't the most convenient base town. You may reconsider spending those nights in Bern and just spend all of your nights in or near Interlaken instead. If you still like to travel to Montreux in that case, consider the Golden Pass line.
