If you have a superuser account (common username is HOST) you can login and go to the Host menu, and see if you have an EXTENSIONS page listed, from that page you can see what version of DNN you are on. you can also try the HOST/HOST SETTINGS page.

If you don't have HOST access you are going to find you'll be limited in being able to install additional skins and extensions.

If you have an ADMIN login (less access than host) you can see if there is an ADMIN/EXTENSIONS page.

As for your other questions.

How important is it to run on the latest version: that really depends on a number of things, I generally recommend it, but the ultimate decision will come down to questions like (do you have custom modules on your site, will those modules work with the latest version of DNN, do you need to address security issues).

As for third party tools to backup the site, I honestly find backing up my website and database manually is my preferred method.

Justin, file properties of dotnetnuke.dll should display the version, besides you may check highest number in dataprovider filenames inside folder /Providers/dataproviders/sqldataprovider
