I upgraded to Wordpress 3 and Atahualpa (3.4.9 according to my wordpress dashboard). My left side bar disappeared and I no longer have full posts on my blog like previously. I also went into my GoDaddy account and it looks like all the old data was over-ridden so no pictures for the header. Does this sound right? Anyway I could back back to my old version of Atahualpa, as that looked great? Thank you for your time.

If you didn't do a backup of the wp-contents folder before doing the update (as wordpress cautions you to do) you have lost the images unless they were backed up somewhere. You might ask your host if they can recover the files
