@# is the row number, so to refer to that row, you need @@#. Something like this,
although I didn't test to see if everything gets parsed correctly:
#+TBLFM: $2=if(2 == @#, 0, remote(my-table,@@#$1))::$3=if(2 == @#, 0, remote(my-table,@@#-1$1))::$4=if(2 == @#, 0, (remote(my-table,@@#$1)-remote(my-table,@@#-1$1)))
Turning on formula debugging with `C-c {' helps.
