Hi Benjax,
You can buy the tickets at any time, they don’t sell out. However, buying early can be cheaper if you buy a Saver Day Pass instead of a point to point ticket. You basically don’t buy a “Glacier Express ticket”, but a ticket to get you from A to B, with any train. The reservation you already have allows you to take the Glacier Express. The below pages explain about all options and also links to purchase:

Hi Benjax and Welcome to MySwissAlps,
If you have a Swiss Half-fare Card you will most certainly find the SBB Mobile app (bit.ly/2ICIUHi) very useful for checking train, bus, boat and cable way timetables, finding fares* and buying tickets on-line if required. In the unlikely event you don’t have a device capable of running the app then you can use the timetable on the SBB website (bit.ly/2HH1U7B). If you are not familiar with using the SBB timetable it is worth first reading the instructions at http://www.myswissalps.com/timetable.
* The SBB website shows half-fare prices by default, the mobile app allows you to nominate whether to show full or half-fares (by editing the passenger details in settings) and is also smart enough to offer you the Saver Day Pass (http://www.myswissalps.com/saverdaypass) if that offers the best fare. The app can also display a platform map (at least at the larger stations) to help you make connections. You can also easily filter modes of transport (eg bus or ship).
The app (or website) will always show the fastest, most direct routes unless you tell it you want to go a longer way round by including other stations to go VIA. For example, if you wanted to follow the full Glacier Express route you would need to search the SBB app looking for Zermatt to St Moritz via Andermatt..
