Your apps should be in your iTunes library so they can be synced back to your phone after restoring. Your messages will be contained in your backup so if you are careful to make a backup at the beginning of the process (step 6 in this article: http://support.apple.com/kb/HT1414), at the end of the process when your phone restarts and you set it up again you will be given the option to restore it from this backup (see photo below), returning your messages to your phone. Be sure to back up your contacts before restoring as they are not fully included in your backup. Options include syncing them to iCloud or Google or using an app like My Contacts Backup (which will back up your contacts as an attachment to an email that you send to yourself; you can later open the email and tap the attachment to import your contacts back to your phone).
