A quick look at the SBB timetable shows regular summer boat connections from Alpnachstadt to Vitznau with only one change of ship usually at Verkehrshaus-Lido. If you look under "Advanced Search" you can filter for ship only connections.
You can go up one side of Pilatus and down the other. For what you have in mind I suggest up via Kriens and down the other side to Alpnachstadt then take your lake trip to Vitznau. From there you can return to Luzern by boat or bus with an option for train part of the way. The whole trip is on your Swiss Travel Pass.
By the way, the Swiss Travel Pass may be a new name but in Switzerland you'll often hear it called by its old name of Swiss Pass. That's now a different thing for locals. It's easy to get confused!
