I've read about folks keeping 2-3 main vines on an indet. tomato plant. My first year tomatoes have the same, and now I'm pinching off all new sucker shoots. I'd leave it.

Leave it. If you prune it now, you risk sun-scald.

I got it from a local high school greenhouse and they obviously weren't taught to pinch the "sucker" shoots,

Thank heavens! I'd hate to think they were being taught that pinching off suckers was required for some reason.

Plants healthy and doing fine, no need to prune unless later this month you want to grow a 2nd plant from a sucker.

I never prune my maters, just put them in huge cages, and always have massive harvests. Pruning is really only needed, IMHO, if you are using a single stake per plant. It's a personal thing, though :D

I just assume that a plant grown naturally, the way God designed it, will produce better if left to grow the way it was programmed to, with little or no help from me, other than weeding, mulching, and fertilizing :D

Your milage and opinions may vary.
