Hi
I'm reapplying this year again too.
As for the statement, what one of my professors recommended was to write a new statement, even if nothing much has changed in regards to your practice, because after all, a year has gone by and by that time you have likely changed as well as your perception and views on your own work, or the theoretical framework etc. And if you then still prefer the "old version" of your statement, you can still just leave it as is.
As for the others, it really is just personal preference ig and what the school is asking for in a portfolio specifically.
Either way, good luck for this years application!
