You're using double quotes for strings instead of single quotes. Double quotes indicate a column name, and single quotes indicate a string. Try this:
Insert into Customer (Customerid, Username, Fname, Lname, Street1, Street2, City, State, Zip)
VALUES (42, 'Guitarhero', 'Wes', 'Montgomery', 'Mainstreet', 'Manhattan', 'NY', 12304);
Also note that you're using uppercase letters in your table and column names, but those will be changed to lowercase by postgres unless you put them in double quotes.
