The VIP panoramic seats are only available on certain trains on the route Zweissimen <> Montreux, not on Luzern to Interlaken and also not on Interlaken to Zweissimen. On the Golden Pass website, these are the ones where the locomotive is shown in the middle of the train, not at the front or back.
The VIP seats are the ones at the very front of the front carriage (numbers 81-87).
I think it not so hot in this very modern trains. You can bring some water with you to drink.
Luggage can stored in the train, also near the VIP seats.
