Which QB and 3rd receiver would you start in Week 5?

I play H2H and have Kurt Warner vs Houston. & Ben Roethlisberger vs. Detroit. Who would you start? Also, I'm starting Steve Smith (NYG) vs. OAK and Mike Simms-Walker vs. SEA. Now I need a 3rd receiver. Would you start Calvin Johnson vs. PIT or Chad Ochocinco vs. BAL?
