You don't need to book seats for trains in Switzerland. Your outbound trip most probably requires seat reservations for the train crossing the Swiss-Italian border. You can check that in the timetable
, and more details about booking seats can be found here
. Rail Europe allows to book seat reservations for "pass holders". They do indeed not list all passes, but assume that you have any pass that allows free traveling for the leg you're booking. A Swiss Pass would in this case be identical to an outbound trip with a Swiss Card, as both of them offer free traveling within Switzerland. You can book seats and tickets via the timetable as well by the way.
I would not get another pass on top of the Swiss Card, unless you want to do some extensive traveling on the free travel days the regional pass includes. Otherwise, the discount you get with your Swiss Card would be sufficient.
