As far I know, you do not need any cover letter, because everything you are going to write in your cover letter are already mentioned in the online application, so you can answer it therein.
Yes, my common sense is telling me that you shall be filling up two separate applications for you and your spouse and the interview (if needed or held) it might be on the same day, but I am not sure if they are gonna interview you together, obviously they should interview you separately in order to know your genuine intentions in visiting the United Kingdom.
Finally, organizing documents, well, personally I am looking for this answer as well. Next monday is my appointment at Gerry's and I have no clue how to organize my documents, but I did arrange it in some order and make an index for it by putting together different documents in each different category like, personal, financial, proof of evidence, accommodation etc.

Cover letter is not mandatory but it supports your application. If you have some extra information that is not being disclosed in the online form. You must attach any document which you feel that it will support your application. Like who is funding your visit. They will organise but better you have seperate all by the heads e.g finance , accommodation etc
