@samikdg I'll answer this in points:
1. I am not sure if you can challenge them for the equivalency (I mean you can challenge them, but not sure about the outcome of such reviews), but you can definitely take your degrees to IQAS and hope for a different outcome (research first on these forums, am sure there's an answer lurking out there).
2. Not sure if there's any NOC that's into Knowledge/Content Management (My primary NOC is 5121 and secondary is 5122. However, my experience matches the responsibilities given there perfectly). It would be great if you could DM me her job responsibilities, i'll help you accordingly.
3. The money bit you can execute an affidavit stating that the money in your account can be used by your wife, no need for gift deed.
