Welcome to toddlerhood, dear. As a child approaches the second birthday, his/her sole desire is to control the universe, one parent at a time.
Granted, cutting the 2 yr molars is hard and painful work, but motrin/advil should solve that problem.
Refusal to go to bed is simply an act of gaining control.
At 2, he still needs an afternoon nap. Napping really shouldn't be an option until about 3 1/2. Even then, you should still enforce a "rest time" in the middle of the day.
Also, at this point, if he's staying up way late, he's missing some good sleep, even though he's waking up later.
I would begin by backing the bed time up to 8:00, and I would not, under any circumstances take him out of his crib after you've put him to bed. When our son hit this point a few months ago, we did concede the fact that we can't make him sleep, but we can make him stay in his room. So, we let him have a bedside lamp on, and gave him a few board books or a toy to play with. The Leapfrog "Baby tad" is good for this. anyway, we put him to bed with the regular routine, gave him his blanket and let him wind down with his books or toy. Then we established a "lights out" time about 10-20 min afterwards.
It does become difficult for kids this age to settle down and sleep if there's still activity in the rest of the house that he thinks he's missing out on. So, we have made it a habit to turn off all the surrounding lights -- hall, bathroom, etc. (anything that would cast light into his room), and stay at the other end of the house for a while (load the dishwasher, work at the computer, chat about our days, etc.).
Yes, he cried at first, but no amount of crying should get him out of his crib. We would go in and comfort him, but bed time is crib time, end of story.
Now he stays in his room after bed time and is generally asleep with his board books on top of him before I can get back in there for lights out.
