Hello Czunder, welcome to MySwissAlps!
You are referring to the Swiss Transfer Ticket, am I right? This ticket type will no longer be sold in 2019, but if you buy it in 2018 you can still use it in 2019. Rail Europe and other purchase options are listed here: www.myswissalps.com/sw isstransferticket/pric e.
Seat reservations are a separate thing, regardless of which ticket or pass you're traveling with. Seat reservations are uncommon in Switzerland, except for a few tourist trains. Please find details here: www.myswissalps.com/tr ain/reservations. If you would like to reserve seats anyway it will cost you at least CHF 5 per person per train, which would be CHF 80 for this trip (2 trains, 8 people). But again, it is not needed. You can always board.
