I think you need to think more about what you are trying to achieve, rather than mechanically following the steps you have been shown.
I suspect you have been shown many examples in school, all of which have given you a wind component. You seem to have forgotten that you don't, in fact, need to calculate the wind component at all. You are using it to find the groundspeed, but if you are given a wind, a TAS and a track then you find the groundspeed directly from the CRP-5. The groundspeeds out and home need to be found for PSR, but as pointed out above the track home is the reciprocal of the outbound track.
Considering winds, remember that wind components on reciprocal tracks are never the same magnitude unless the wind is straight down the track. You will always lay off drift by turning into wind, increasing any headwind component, reducing any tailwind component. If the wind is at right angles to track the wind component is headwind either way!
