If it is like that I have the feeling that you will like it a bit more, at the very least. And about what you asked, the stuff that gets transfered is:
-MC's Social Stats and Persona Slots.
-Money
-Persona Compendium
-Items that you get when your S.links reach Rank Max (S.links resets, btw)
-Costumes
-Skill Cards
Oh what the hell? I guess that means playthrough 2 is going to be doing nothing but rushing through social links. At least keeping the stats will eliminate the need to work and study.
