Since you will be joining the March filers in a few days, I believe you have not started filling out the forms online. When you start you will see that it will be pretty straight forward and you will not even upload that much stuff.
For example, the only time I ever uploaded pictures of me and my wife was the first application on the I-130, after that, never uploaded a single picture. I'll still take them to the interview in case they ask for them, but there's no need to over do it, do send too much information, just what they need.
