I hear it often, and can usually derive a sentence's meaning with or without it. What does it really mean? When would one use it?

It means 'whether or not this is of any use/value'.
means, for example, that it may not make any difference to the physical state of the window, but that hopefully the apology helps placate you.
It's almost a kind of self-deprecation; it's saying 'No words of mine will be adequate, but...'
As reported from the NOAD, for what it is worth is used to present a comment, suggestion, or opinion without making a claim as to its importance or validity.
