Can't Get to Admin Panel; CSS not loading

I am a self-taught novice who knows enough to get by, but who has holes in his game and got myself into a mess!

My site uses the twentyeleven theme. Two days go, I was updating my site (www.furyfc.com/blog/) after a long period of inactivity. I had things working well. Then, for whatever reason, I got a bit too daring and tried to make a showcase page that was already called “Home” the first page that you see. Through the WP admin panel, I went to Settings>General. There, I manually changed the WordPress Address (URL) and the Site Address (URL). I believe I changed both to http://www.furyfc.com/blog or http://www.furyfc.com/blog/. I guess it’s even possible that I changed both to “www.furyfc.com/blog/?page_id=127”? In addition, I went to the Settings>Permalinks section, clicked the “custom structure” radio button, and likely changed it to http://www.furyfc.com/blog or http://www.furyfc.com/blog/ or http://www.furyfc.com/blog/?page_id=127. Around that time is when everything went wonky. The site/blog is not loading CSS and I can’t get to the admin panel.

I got my host to reload WordPress and then to do do a full restoration to 3 days ago, but neither one helped, and they say this is outside of their scope.

When I look at the pages on my site through Firefox’s developers tool, stye editor, I see that WordPress appears to be interjecting “?page_id=127” into the file structure on my site (see below). I assume that’s why the style.css file is not loading, AND why I can’t get into my word-press admin Panel to fix this. I’ve bolded the first unexpected instance of /?page_id=127/ to show you what I mean when I say it’s interjecting that into the file structure. Any ideas for a fix??
