Doc Information on Template
While DokuWiki's default template doesn't allow you to hide those things in the configuration, there are templates (and very popular ones) like the Bootstrap3 template which allows you to configure whether that data is displayed or not.
You could also just comment out line 64 of [your DokuWiki directory]/lib/tpl/dokuwiki/main.php
Page View Counter
As for a page view counter, try this plugin: plugin:accscounter
If you want more analytics, you should check out other plugins with tags such as stats and what not.
