The 1st Class STP allows you to ride free in 1st Class. I found 2nd class perfectly acceptable. There is no 1st Class in cable cars, cog-wheels or buses so you pay extra for 1st Class STP for no benefit.
If you have a 2nd Class Pass and want to travel in 1st you can just buy a Class upgrade for that trip. e.g. to gain access to upper deck in Lake Lucerne steamer.
Reservations are not necessary with STP or any other form of Pass or ticket in Switzerland. The only exceptions are the major Panoramic trains (Glacier, Bernina and Gotthard Panorama) where reservations are compulsory.
Make sure you understand the validity map downloadable from www.myswissalps.com/sw isstravelpass/validity.
For all the mountain excursions show your Pass at the base ticket station to get a free or discounted ticket.
