Okay, soror.
ANY tour of Charm City begins with the Inner Harbor area with its many restaurants, shopping venues and museums (such as Port Discovery, Maryland Science Center and the National Aquarium). Other must see attractions outside of downtown include the Great Blacks in Wax Museum, the Benjamin Banneker Museum and the Hampton Mansion with its authentic slave quarters.
I don't know of any particular websites to point you to but a web search should yield a lot of information regarding the above.
