I'll try to answer as much as I can:
Clothing: no need for a goose down jacket I would say. A wind breaker with more layers under it will work fine in higher altitudes. The key is multiple thinner layers so you can adapt to the weather each day or even throughout the day: myswissalps.com/ weather. You can get by on sneakers if the trails are really easy. As soon as there are rocks, gravel, etc. I would prefer solid hiking shoes.
Temperature: it can be -5°C if you're on a peak on a bad day or early in the morning and it can be +35 °C in the valley during a hot day. Temperatures can vary a lot by the day and by altitude. On average it will be pleasantly warm to even too warm in the towns in August.
Itinerary: I don't think you should add more. You will visit some beautiful areas and only have limited time in each place. Do come back for more another time :-)
Scenic trains: you will not encounter trains with required seat reservations. Please see myswissalps.com/train/ reservations and myswissalps.com/activi ties/scenictrips/train. Please see here for where to buy your Swiss Travel Pass and here for the current promotions.
Prepaid card: please see myswissalps.com/simcar d for SIM cards and a portable wifi hotspot.
