Do you have a recent backup of your catalog? If yes you can restore the catalog from this backup.
If not, you've no chance to get all editings and settings back.
The photos you've edited in Photoshop you'll find as psd or tiff files in the appropriate folder(s) and from there you can reimport these.
I've create a backup of the catalog on every time I closed Lightroom. It may take some time, but I'm on the safe side and I don't loose so much work.
