Hello 1stTime. 15 minutes should be enough to catch your TGV train. You should reserve seats in the TGV train in advance, so I wouldn't recommend to buy your tickets on the spot. If you want to have more time, you could choose the earlier connection with a Golden Pass train on the leg Zweisimmen-Montreux (leaving from Zweisimmen at 08.26am). This will get you in Geneva at 11.24am. That's early of course, but it's up to you. There are several connections in between too, but regular trains are involved here and not the special Golden Pass carriages.
There seem to have been some technical error with the official SBB timetable the last days. When requesting a price, the timetable returns an error. However, if you hit the 'back' button of the browser and try again, it does work. I hope that helps!
