Five nights in Lauterbrunnen area is definitely not too much! In fact, with five nights you will just be able to scratch the surface of what the area has to offer. Especially with pre/teens. IMO, it is the most scenic & gorgeous region of the country and, as you've likely already discovered, ground zero for adventure sports.
Unless there is something specific that draws you to either Zurich or Lucerne I'd skip both in favor of heading straight to Jungfrau Region. Both are nice cities but not a lot in either to attract children with a taste for adventure sports. Certainly not as compared to Lauterbrunnen area.
You will need a transport pass to cut travel costs. There is a great overview of available passes here www.myswissalps.com/tr ain/ticketspasses. My personal favorite is Half Fare Card. It's easy to understand and use. 50% off of all forms of public transportation (train, bus, boat, gondola, cable train, etc etc) You and the 16 year old will both need one. The younger children will travel with you for free with the Family Card. The Family Card is free but you must request it at the time you buy your HFCs.
In addition to the very informative links Steph has provided you may want to look at this as well: www.myswissalps.com/fo rum/topic/tips-about-wengen-and-the-jungfrau-region-by-kim
