Even though you are installing from discs, there is a bunch of downloading that is required to patch the client up to the latest release build. These patches are installed automatically. If you choose not to patch the client, then there is no way for the game to be playable.
While downloading the patches can be quite internet bandwidth intensive, it is a one time thing (unless you have to reinstall the client). The game itself does not take a lot of bandwidth.

It depends on the app. Some like Skype or Facebook will not work without an internet connection to work. Some like Evernote can work with or without an internet connection but will require you to connect at some point. Some like the Angry Birds game do not require an internet connection to work. All apps will need to be installed somehow and the most common way to install an app is by downloading it from the Google Play store. So, the answer to this question is - it depends. So do, some dont.
