Welcome harry103, thanks for joining us!
You're right, there's a large choice of rail passes and tickets, and that can get confusing. However, I think you managed to pick the best option for your travel party. Swiss Transfer Tickets will cover the journeys from Zurich to Grindelwald and from Wengen to Zurich, and the 15 year old will travel for free with the free Swiss Family Card. Information and retailers are listed at www.myswissalps.com/sw isstransferticket/pric e. For US residents, the cheapest option is www.raileurope-world.com.
I too would recommend the Sportpass for your specific plans. If you plan to focus on the Jungfrau region and plan to use public transportation and ski lifts intensively, it should be worth buying them. Note that there are three variants: all of the Jungfrau region, Grindelwald-Wengen (which excludes the western side of the Lauterbrunnen valley) and Mürren (which excludes the Grindelwald side). You should either pick the Grindelwald-Wengen variant or the Jungfrau variant. If you want to tell for sure which option is best, you should try to make calculations as explained at www.myswissalps.com/tr ain/ticketspasses/prac tical/chooserailpass.
