1. If you are willing to write up a history section for us, you are absolutely allowed to do so. If your written history is sufficiently in depth, you don't need to link us an outside source, but if you feel the Marvel Wiki is a good source of information aside from the arcs you mentioned you are free to link and and then write your history for said arcs, as long as you label it accordingly.

2. Fury will begin to age again, but it won't be all at once. He may wake up to discover that he doesn't feel quite as young as he used to be, but his body will remain as young as it was physically. He will not age rapidly, but essentially time will start for him again.
