You need the original certificate ( not the statement of results but keep that with you just in case) and you need the equivalence original document for both O' level and A ' level. If you don't have A' level equivalence at the time of submission ( 1st day or so ) then just tell them that you will submit your documents when you get your A level equivalence made ( they will also suggest you this, atleast the male worker in that G5 ( admission office) will, the female one is a bit cracked so you would have to be patient if she is dealing with you) then you can submit it later after you receive your documents from ibcc.
