I think so much depends on the sleep personality of your baby - it can be really hard to plan. We got a crib for the baby because that was what we were supposed to do...but more often than not it held laundry more than the baby. That being said, it was nice to have a place to put DS when I needed to use the bathroom (he absolutely loved cooing and talking to his mobile), and when he got bigger we side carred the crib to the bed to give us all some more space. He never slept in the crib. Even though we got one that converted to a toddler bed, he just wasn't the type that was cozy in it. We went straight to a mattress on the floor ( at around 8 months for naps), and now he sleeps in a regular bed (with rails). He just turned two.
But my son had a ton of sleep "issues", and would only sleep on my chest for the first several months of his life. Even now he has nights where he needs to be nursing or touching me at all times. But if your DH is worried about having alone time with you, and your baby is okay in the crib, you can start off the baby in the crib for the night and then bring him or her into your bed at the first wake up. You can start that from the beginning, or whenever else it works for you. Also, it might be good to have a place to put the baby for naps. I wouldn't necessarily run out and get one now, but it may be something that you consider getting at some point.
For your DH, I would show him some stuff that supports co sleeping, and let him know that you are taking his needs into consideration too. And keep in mind that nothing is set in stone. Some things are going to work at some stages, and and other things at other stages, so it's okay to experiment and see what works for you. I know it can be hard because we really want to plan and make sure that everything is "set"...but babies will ALWAYS throw you through a loop somehow or other ;)
I'm not sure if the link works, but this is the post I had my DH read, and it made a lot of sense to him. (If you go to the "soapbox" section, click in the "Is your child sleeping through the night?" post).
