1. Don't get a black suit, unless you're planning on forming a Blues Brothers tribute band or Ska revival. Navy, charcoal, maybe a lighter grey too...these are your friends.
2. The darker shoes will work well with a lighter grey or navy, but a little casual. You need a black cap toe. That's your number one shoe friend for all formal occasions, interviews, any business suit, and even black tie ("tuxedo" if you're American), if needed. A brown shoe is a less dressy option with blue, grey etc., and the second shoe you buy.
3. But don't buy any of the shoes you pictured. They are utter shit. Get a goodyear welted shoe from a reputable retailer and learn how to polish it. It will be money far better spent in the long run, and if you're smart, you can pick some up for as little as $100.
