I didn't have a room for DS, I just had DD's cot in my room but we ended up co-sleeping. As far as packing I had 3 or 4 of both 00000 & 00000 suits in a bag. Everything else for hospital got packed when my waters broke.

ETA- we put DD's new carseat in the car 2 weeks before DS was born because she vomited in the convertible one & I had to take it out & wash it. We put it back together & back in the car just before we left for the hospital
