So anyway, what does a zero-clue newbee (like me) need to know about ads on a page ?

Read your advertising network's terms and conditions carefully and take them seriously. Many problems come back to T&C breaches, usually committed in ignorance rather than with intent.

Don't expect to make much money, from your description you will be lucky to cover your hosting costs. You need a web site that generates a lot of traffic before you start getting a decent return.
