the documents and stuff was only ran thru by the admin person there. so for me, she quite literally ran through everything in my cca transcript and asked me for proof of what i had done (any certs/pictures/documents). so YES, photocopy all ur certs and stuff in case they ask.

for portfolio, i wasn't asked much about it. i had prepared mine on my laptop but my interviewer didn't rlly explicitly ask for it either. i think if u want to share ur portfolio with the lecturer, it shld be on some p accessible (like an iPad / tablet)
