I recommend you travel straight to St Gallen and base yourself there.
Switzerland is a small country and travel times are short, especially between Zurich and St Gallen, as they are both in North East Switzerland.
On arrival at Zurich airport, just go to the Flughafen railway station and take the first available train to St Gallen. Trains run four times per hour (two fast and two semi-fast). The fastest trains (2 per hour) take just 45 minutes.
From St Gallen, you can get to Rhein falls in about 1hr 20 to 1hr 45. Best route is St Gallen - Winterthur - Schaffhausen (or you can go via Zurich)
St Gallen to Stein am Rhein is a direct local train (no changes) taking 1hr 20 minutes, following the northern edge of Switzerland along the Bodensee (Lake Konstanz)
