System Preferences Appear Corrupted

Try deleting com.apple.systempreferences.plist in your Preferences.

Possibly also com.apple.finder.plist.

Try booting in safe mode and see what happens.

Not sure what to suggest. It is obviously localized to your own account so there's something that needs to be removed. The only possible other plists that might be involved with opening System Preferences are the ones in ByHost within your Preferences folder. But wiping all those all out is a bit radical.

I suppose you could experiment by temporarily renaming ByHost, say as ByHostX, and then see if your system preferences successfully open. If that worked at least you would have localized to something in the By Host folder.

Even more radial would be to temporarily rename the entire Preferences folder.

If the other existing user account is working OK, the new one should as well.

Unless you import into the new account whataver is screwing up the current account.

Moving stuff can be a bit of a hastle if you don't know everything to move. You can move apps but if you don't move the preferences and anything else associated with those apps at a minimum you would have to redefine their preferences but you could also miss other stuff those apps may have installed in /Application Support and other places. Itunes lib can be copied but you then have to tell itunes where it is. Photos I don't know how you do that.

I never had to recreate nor move an account so I am no expert at it. And when I set up a new machine I know everything involved with each thing I move so I have no problems moving those either.
