The Lautertbrunnen to Murren section is a two stage trip. The second part is a wonderful little train (some might call it a tram or a trolley) that wanders along towards Murren. The views are magnificent.
The other option is the cableway and bus via Stechelberg. Different, but also magnificent, scenery from a lower level.
I did the round trip you plan in 2015 on a wonderful cloudless June day.
The restaurant at the top of Schilthorn is a wonderful experience and, as I found, not really any more expensive than elsewhere in Switrzerland. But, considering for most, it's probably a once in a lifetime experience it's "worth every cent".
And don't forget to say hello to James Bond.
Enjoy your travels!
