I'd stick with the cage too. It's about the size of the one we have for our new baby. The one we have for our other hedgie is even bigger and I love it! It may seem too big but I'd rather they have more room than they need than too little. Plus you never know what she's doing at night! 
Once you have the wheel, litter box, hidey hut or bag, food and water dish, and toys there shouldn't be much room left in there. I've also added little tubes and both hedgies love to crawl through them or over them. They are like these (minus the fuzzy bedding of course) http://www.drsfostersmith.com/product/p ... atid=14596 and come in a few sizes. Using liners will make a HUGE difference for cleaning so I'm glad you've decided on them as well. If you aren't sure that she's using the wheel, some people have mentioned dusting a bit of flour on it before you go to bed and then look for any footprints etc. in the morning. You can also try luring them onto the wheel with their favorite treat just to get her used to going on it.
Best of luck to you!
