A grown-up bedroom

I would love to have a grown-up bedroom. What I mean by grown-up is having all the necessary furniture, preferably matching (or at least intentionally mis-matching), with an actual bedframe with a headboard and matching bedding instead of whatever random old blankets happen to be clean. Before this weekend, none of this was the case. We don't even have end tables. Until my brother moved out and I got my dresser back, my alarm clock and lamp were on the floor by my bed.
Thanks to Linens 'N Things going out of business, I am one step closer to my dream. We bought this bedding set at a very reasonable price:

In real life, the green is much more vibrant than it looks here.
Still considering options for (and saving for) a headboard. Maybe something kooky like me...

Or stick with the straight lines and modern look (I'm leaning toward this, especially since I can make it myself)...

And green walls and cream drapes and chocolate furniture... hmm...
