Wow....I guess this a big day for you and a hearty congratulations will be in place.
It's really great that all you have is anticipation and you don't seem to be nervous at all... Most first time parents are usually scared as anything.
I would actually not suggest rushing the labour but let it run naturally, I guess you'll be told that in the hospital as well.
And yeah, don't let her remain confined to the bed. She can walk around if she wants to or take any position that's comfortable for her. Pacing actually helps uterine contractions as well.
Hope to see the baby's face here soon. :)
