She sounds like she's doing very well.
Two is very young to be dry through the night - lots of people treat overnight and day time as 2 differant things when it comes to TT and get daytime down before overnight.
If she's wanting to jump down off the loo really soon maybe you could get her a book or two so that she's more entertained while she's waiting for some action. Also a warm drink can stimulate the bowels so maybe if you give her a warm milk or water just before you pop her on the loo it might make her more likely to poo before she jumps down.
