Need help decorating for baby.?

I'm due in four months and we rent a two bedroom apartment so we can't paint. We haven't decided which bedroom to use yet, but our two options are either an olive green room with windows or a soft chocolate brown color room with no windows. The trim is dark oak and the carpet is a lighter shade of brown. (Oh yeah, we're having a little girl!) I haven't been able to find much online as far as decorating for baby rooms or nurseries. Any recommendations for websites OR any color schemes that would work with either of these would be awesome. I feel like if I have some ideas to get excited about it might help me get motivated and encourage conversation about it with the hubby. At this point we haven't talked much about it because it's such a daunting thought (one bedroom is used as ours, the other is a VERY messy office). Thanks!
