Hi sanetvs and welcome to MySwissAlps!
No, you do not need to make reservations on this train. You can buy the Swiss Travel Pass at any Swiss railways station office. It would be more convenient to buy it online here and have it emailed to you for printing at home – that way no offices and lines to deal with as you are good to go upon arrival in Switzerland.
Trains run pretty much normally on Sundays – you can check the schedules for your planned trips here.

Thank you! I tried to find a connection between chamonix and martigny, but it keeps saying “no connection possible” or there is only bus services available.

Yes, you would take a bus to Le Châtelard-Frontière and then a train to Martigny.

Where were you looking for your connection? If you use the Swiss Timetable, for which Lucas has provided the link above, it shows you can go the whole way by train on 3 September 2017 (see attached).
Between 3 April and 24 June 2017, there is a replacement bus operating between Chamonix and Châtelard due to implementation of a new signalling system, but that should not affect you if you are travelling in September.
