For #1, though I don't remember what it was, I know JC (who owns this site) had a reason for putting Brutal mode in the way he did. I think it might have been that he wanted the ability to show and mix both regular and brutal mode scores, which is what currently happens by default - it shows whichever score is better, normal or brutal. If you click "Show Brutal Mode" it shows only Brutal scores. This lets people who want to see only Brutal still do that, and people who want to see purely the best scores also do that.
For #2, that's definitely something I've been meaning to do. Definitely coming soon. We're planning to add same little graphic that the game shows to indicate an FC. We haven't discussed FC count stats, but I don't think it would be too tough, at least for RB4 since it has an FC check box.
