Use the cropping tool and click perspective. It lets you stretch the corners our to make things straight.

I only have photoshop 7 and use the stretch and or skew tool. In the future you should avoid this problem all together by using more megapixels in your original shot and include more of the background. If you crop to the center of image, there is less distortion on the boarders. This will make a much quicker fix.
Round walls? I think you need construction workers, not photoshop.
Sure use the bluring tool and blurr the wall into a rounded shape
You can use the warp tool. Change the image into a layer by double clicking it in the layer menu on the right of your screen. Click Edit, then Transform, then Warp. There will be a grid overlaying the image. You can pull the image into the right shape from there. Hope this helps!
Here's a good tutorial that shows you how to use the cropping tool to fix perspective: http://www.escrappers.com/perspective.ht...
