Generally, it is sound advice to buy three. A 22 can, 30cal can, and a 45 can. Those will cover most of your bases, save for some oddball bigbore stuff. The one size fits all cans like the Griffin Bushwacker as an example are cool from the standpoint that they can literally be one can to rule them all, just at the end of the day that kind of functionality isn't all that practical. YMMV.
In regards to a trust, the only people who have to submit prints are whoever the "responsible persons" are on the trust, AKA trustees. It is generally understood that you can add trustees to a trust with a simple amendment (Silencershop's single shot trust for example comes with a pre-made amendment for adding trustees) after the form 4 has been approved without having to send in additional paperwork.
