Lock other people out of your greenhouse - in my experience they almost always cause trubble!!!
That being said, he was right about removing leaves and flowering shoots from your tomatoes at this time of year, the plant will concentrate on ripening the existing tomatoes. It's too late in the season for more to form and grow to ripening.
But he was wrong about the tomatoes not pollinating themselves - tomatoes do just that - although in the greenhouse they may need a little tap on the stem as you walk past to replicate the breeze or the action of insects buzzing around that happens when tomatoes are goring outside.
