Twenty Eleven Sidebar with Events Manager

Two part question.

1. When I make my theme layout two-columned with content on left, and try to add the events manager calender widget to the main sidebar, it just shows up underneath my posts instead of floating to the right.

2. Is there a way to only show a right hand column (with this calendar and maybe a little “featured images” gallery) on my home page, and make all the other pages single columned?

Thanks!
