I think the Belle/Shadow situation was Peter playing mind games with Rumple, trying to get him to admit his feelings and fears out loud and to Peter's ally. It gave Peter a slight advantage, and he knew he might be able to influence Rumple's decisions by having the Shadow pretend to be Belle, someone whose judgement and reasoning Rumple trusts with all his heart.

At least, that's what it seemed like to me.

Also, about Peter flying, I think he used up most of the Pixie Dust by flying, which is what he loved to do, what he used to dream of. The Lost Boys said that Peter's Thinking Tree is where the Pixie Dust used to grow. Peter must have realized that his supply of Pixie Dust was limited and preserved it in vials to only be used when necessary. That's why he doesn't fly until Think Lovely Thoughts, after Henry gives him his heart. The Heart of the Truest Believer gave Peter enough power to fly at will, however briefly. If Peter had had time to absorb all the power from Henry's heart, I have no doubt he would have been able to fly whenever he wanted.
