As much as you'd like to, you can't cheat the system by copying over the android_secure folder, lol. It is secure, after all. You'll have to either redownload everything or seek out an app designed to back up application data with/without root, depending on your situation.
Also, if you had done the setup wizard when you first got the phone, it would've redownloaded all the apps connected to your account, some possibly with data backups (Google does this as long as the developer took time to implement it).

If it ain't broke, use a sledge hammer.
