Custom Google Search breaks my sidebar?

I’ve installed the CSG plugin and I like the results but there are two things I really need help with, please.

When including it in my sidebar it forces the entire sidebar to go below page content rather than staying on the side of the page. How do I prevent this?

I’d like to be able to style the search results page just a bit – most notably, the font size and # of results displayed. How can I do this, please?
