Let us know how well your shock and struts hold up. Are they factory? Some don't last long after lowering.
I would love new springs without the lowering due to our deep snow and back roads. The ride is a bit bouncy for me with the stock set up. I can see the Legacy needing springs, shocks, struts, bump stops, bushings and upper mounts.
Looks good. Good start to improve the handling and ride with a new set of springs. Enjoy.
