Your 3dTshift warning about datasets already being aligned in time suggests that the slice timing information is not included in the dataset header (this is actually pretty common). You can specify a timing pattern using:

-tshift_opts_ts -tpattern alt+z

replace the alt+z with your actual slice time information

             S L I C E   N U M B E R
   tpattern    0   1   2   3   4   Comment
   --------- --- --- --- --- ---   -------------------------------
   altplus     0 600 200 800 400   Alternating in the +z direction
   alt+z2    400   0 600 200 800   Alternating, but starting at #1
   altminus  400 800 200 600   0   Alternating in the -z direction
   alt-z2    800 200 600   0 400   Alternating, starting at #nz-2 
   seqplus     0 200 400 600 800   Sequential  in the +z direction
   seqminus  800 600 400 200   0   Sequential  in the -z direction

  If @filename is used for tpattern, then nz ASCII-formatted numbers
  are read from the file.  These indicate the time offsets for each
  slice. For example, if 'filename' contains
     0 600 200 800 400
  then this is equivalent to 'altplus' in the above example.
  (nz = number of slices in the input dataset)

N.B.: if you are using -tpattern, make sure that the units supplied
      match the units of TR in the dataset header, or provide a
      new TR using the -TR option.
