There are tons of themes available in this forum.

As for getting wallpaper on your device. Save the image to the proper size for your specific device and then simply e-mail it to yourself.

P.S. Next time start your own thread for a problem which has nothing to do with the topic of the thread you posted in or find an existing thread which pertains to your problem.
