Jens shift lens correction is problematic, it's best done dynamically because the lens correction routines assume that the distortions are predictable as generally the lens characteristics are based on the effecive centre of the lens being at the centre of the frame. If a lens is tilted or shifted this is no longer the case. Instead you can use a program such as Hugin which allows you to set control points on vertical or horizontal elements in the frame which can then facilitate remapping of the frame in order to negate distortions.
