there is a part with abunch of angled struts coming out of the wall- it is a dark area, there a several tuskens and i think there is a trandoshan in the front of this area, right befoe you go into it.
anyway, behind one of the raised sections is a grate. slash it open, go through, and follow to you reached the 'blue' room. the right side of the wall is where you jump up. and up. and up...
