There's not a lot of certainty with those SPs, although you have got them for good prices.
SBs look OK with Giles, Jeter & Sizemore, plus Crisp on the bench.
While it obviously depends on who's available, I would look for a sleeper SP to spend that last buck on. Are the uber-prospects (Bailey & Hughes) eligible for the draft? If not, what about someone like Sowers or Pelfrey?
