you dont want to make any mistakes and have the application returned to you.
Ask away on the forum for any questions on any bits of the forms.

I have a masters degree and there were parts that I did not understand to well. :'(
READ READ READ all the paperwork over and over. We initally filled out the forms on our honey moon and then redid them. We made a couple of mistakes the first try.
And for evidence of your relationship, as much as possible is necessary. Phone bills that shows calls to each other, facebook messages, hotmail messages, text messages, pictures of gifts, send in christmas cards that would of been addressed to both of your by family, cards that he would have given to you, if your name is on his life insurance, his health insurance, visa etc..all that is evidence, you want to prove that you are not just 'roommates'. Letters are also good. Pictures of you attending his christmas function, valentine day, birth days, going out with him and his coworkers/friends, vacations, blah blah..you would be so surprised by how much evidence that you have and never thought about including.
