If I get Halo Bassinet what else do I need?

I'm planning on getting the Halo bassinet but I'm wondering what else I will need for more day time use? What item is best to put the baby in during the day when awake? I've heard the rock and play is great, but if I plan to use a bassinet they didn't know if I really needed that too. Then I hear mixed reviews on the mom a roo. Does anyone have advice on this?
