I think you should wait on the potty training. They say that three years old is the best time to start. I think if you start too soon it takes too much time and stress. My son told me just before his third birthday that he was ready to wear underwear. We put them on and he has never gone back to diapers. It took a few days for the accidents to slow down and two weeks before he was fully potty trained. I have heard people say it took 6mos to a year to potty train. That is just insane, two weeks was too much for me. It can be stressful, don't make it any worse by forcing the issue. I think you would probably be better off using the convertible crib and showing her that now she is keeping the crib (some stability) but now it's going to be her "Big Girl" bed (something to look forward to). You may be able to pull off the room change at the same time. Especially if you are going to decorate in a way that will excite her. You can make it her own. Make a big deal about it. Buy her a few things that will make it new but also let her keep her favorite "comfort" blanket, toy, etc. Good luck, I hope these ideas help.
