Agree, original source is always BEST
did you try plugin called “Blog in a blog” http://ww.wp.xz.cn/extend/plugins/blog-in-blog/ I had good fun with it long ago 😉
This is GREAT plugin for what you need, check it out http://ww.wp.xz.cn/extend/plugins/wp-user-frontend/
Not sure what you exactly mean, but have look at this: http://ww.wp.xz.cn/extend/plugins/facebook-image-fix/
I found this theme for download here http ://www.wpsquare.com/demo-download-twenty-twelve-wordpress-theme/
But i also heard it will be part of wordpress 3.5
