Hi,
You can check ,if you open each app that you don't wish to 'go online', that in the settings area of each app if there is an option to disable auto update for that app. That should stop it wanting to update every time you go online.
Also in the Security Settings of the tablet (''menu > settings > security''), check in the ''Auto Start Management'' tab and the ''App Permissions'' tab to see if there are settings which allow you to control the apps behaviour.
