I’m a WordPress dev so might be able to help you 
Pretty much all themes come with pre-defined widget areas, e.g. a sidebar.When you switch between themes, you might have to put the widgets back in, however they will still be available.
You should also be aware that if you switch to a new theme, then revert back, your old widget settings will remain, so don’t be afraid to install a few themes and have a play around.
Here’s a few places you can get themes:
http://www.themeforest.net <- free & premium
http://www.woothemes.com <- free & premium
http://www.studiopress.com <- premium & genesis framework
