Answer 1

Use aliases to give a meaningful description... for example

select 
   tb1.field1 as "Order ID",
   tb1.field2 as "Order Date", 
   tb2.field1 as "Product ID"
   -- ,etc    
 from Orders tb1
 inner join OrderProducts tb2 on 
    tb2.OrderID = tb1.OrderID and
    tb1.OrderID = @OrderID

Answer 2

The easiest way is to use column aliasing, the same way you'd give it another name:

Select 
   tb1.filed1 as 'tb1.filed1', 
   tb1.filed2 as 'tb1.filed2', ... //continue for all your coumns
From table1 tb1
Inner Join table2 tb2 on [your criteria]

I would recommend, however, that you use more decriptive names. Perhaps something like

Select 
  tb1.filed1 as 'RawInitialFiledDate', 
  tb1.filed2 as 'RawReFileDate',
  tb2.filed1 as 'ConfirmedInitialFiledDate', 
  tb2.filed2 as 'ConfirmedReFileDate'
from table1 tb1
Inner join table2 tb2...
