Well an episodic release would definitely be better for us and for you i feel. As for the second question, it really matters what kind of impact the decisions will have on the game. For example if a choice leads to different characters to be used alongside the hero, although i would appreciate it, i wouldn't suggest it as it a huge burden on you, the developer. If the choices are small and lead to different text or to diverge very slightly (like most of the choices in reborn) then i am totally for it (although i wouldn't achieve peace of mind until i explore all the possible choices )
