   Find the reflection v' of v=i-3j+2k around the line i-k
   
   how can I do that? I am extremely rusty with math these days;

   Call i-k = W. I would calculate the vector projection of V on W, call it V_p. Then the reflected vector is 2V_p-V. Draw a little triangle/parallelogram and you will see it.
