My son sometimes gives us a big production at bedtime too (he's 4 now). When we first switched to the bed I would put him back in the crib and just leave the room after 30-40 minutes of bedtime drama. After a few weeks he improved a lot because he wanted to sleep in his bed. You could try a gate on the door (my son would have climbed it). Some days I just sit next to the bed or at the door until he settles down, especially if he is overtired and hyper. Sometimes I read by book light. You can also adjust the naps. My son fought naps and mostly gave them up at 3 but sometimes still would be better off taking one. Usually he wants it just at dinner time and I tell him it is too late for a nap (and try to get him to bed early). It is a balancing act.
