Motorola Droid X :: How To Recover Desktop

I've had my droid x for about a year and a half.I've downloaded pictures two or three times but not lately.The other day I downloaded 900 some pictures, mostly web pictures that I did not realize were in the phone,plus 100 or so of my photo's.I instructed the computer to delete the pictures in the phone.After the pictures were downloaded I was playing a game on the phone when Zap! the screen reverted to the screen that was on the phone when it was new, minus all the icons, apps and folders I had accumulated.The apps were still in the app folder, some were intact, some weren't, such as my audio books inside the book app weren't there. Also now when I talk on the phone I have to use the speaker. No audio what so ever comes out of the ear piece.Any suggestions oh how to recover my desktop(s)? and to get the ear piece speaker working?
