CB doesn't use Joomla view overrides. You'll need to edit the existing Default template or develop a new template. You can find CBs template files at the below location.

In addition how can I show the info text of a field as normal paragraph below the field and not as balloon tooltip?
You can't without creating delimiter fields and using those to explain the field above it. The info icons display is hardcoded like that. Alternative is to develop a new plugin and use triggers to alter the htmledit display of a field to render the tooltip differently.
