To clarify what you mean by the finder bar, do you mean the dock at the bottom of the screen, which has the application icons in it? If so, go to the top left of the screen to the Apple logo on the Menu Bar, and select Dock and either select show or preferences to restore the dock.
Or are you describing the sidebar of Finder, if so, with Finder selected, at the menu bar and selct View, show sidebar.
If you accidently put something in Trash, you can remove it from trash before you can open it again, otherwise, you can empty trash
