Congratulations! This is an insane venture, you know--I speak as a 47-year-old with a two-year-old daughter--but you haven't let that stop you, and that makes me proud to know you.
Now, I have something complementary, or possibly orthogonal, to Bryan's advice--this: http://www.babyhammocks.com/ was a lifesaver for us. It truly did rock the baby back to sleep automatically. It also travels easily--no worse than carrying an electric guitar and easy to set up
It's not too expensive--I believe ours came from eBay for about $150--cheaper than a crib, and durable--ours is currently passed on to a friend.
All the best,
John A
