The Glacier Express is definitely worth your time. That goes for March as well, but it depends on the weather on that particular day whether you get the best views or not. Your plan looks fine to me, except I would personally not spend March 25 on the Glacier Express again. I would stay on board until St. Moritz on the 24th, and travel directly to Paris the next day (takes 7-8 hours). That saves a whole day that you can spend somewhere else, e.g. in Interlaken. Please check the timetable for exact traveling times.
