Resident in Ireland - Non-Irish (Polish Passport) - applying in person

Hi,
I am living and working in Ireland, however I have Polish passport. I will apply for a Chinese visa in Embassy in Dublin, therefore I need to fill in the 'Supplementary Visa Application form' (form v.2011B). One of the questions on this form is to provide a number of residence permit and expiration date. As a Polish citizen, I do not need a residence permit to stay in Ireland. Will it be enough if I tick option 'None' and explain in the form that I am not required to have a residence permit?

I am going to China with my wife. Do we both have to bring our applications in person or can I drop mine and hers on her behalf? If so, do I need to present any written authorisation from her to do so?
Thanks for your help.
