Hi Simon
You don't need to book for a specific shop, you can just use your voucher in any of the three Sant Moritz shops. No problem to collect on the Wednesday so long as you go up before 16:30, just show your rental voucher at the bottom of the gondola and they let you on to collect your skis.
If you miss t then you can collect in the village until 20:00, or the gondola opens at 08:30 in the morning.
