IBDatabase1.Open;
  IBQuery1.Database := IBDatabase1;
  IBQuery1.SQL.Clear;

   //All the examples show
  //  Insert into employee(Field1, Field2) Values('1','Price')
  // Problem is that the entire string has to be in single quotes

  //None of these work
  IBQuery1.SQL.Add('Insert into Employee(PersonID, LastName) Values(1, Price)');
  IBQuery1.SQL.Add('Insert into Employee(PersonID, LastName) Values(1, "Price")');
 
  IBQuery1.Transaction.StartTransaction;
  IBQuery1.ExecSQL;

   // This generates the error - 'Dynamic SQL Error SQL Error Code = -206
   // column unknown
   // PRICE
 
 
  IBQuery1.Transaction.Commit;
  IBDatabase1.Close;

You used " instead of two single quotes for each inline single quote:
IBQuery1.SQL.Add('Insert into Employee(PersonID, LastName) Values(1, ''Price'')');

Sorry, no. This depends on the programming language used, and is no part of SQL specification.
