Editing my wordpress Theme

Hi Guys, proud to be a member of this community. I’m relatively new in WordPress and i’m having a hard time editing my site to my taste, i’m looking for a theme that offers a content area, a sidebar, and a bottom area below the main content area that i can add my website’s featured post, or if there is no such theme, is there any way i could get this done?
