Thank you for your explanation. Especially to b) I have a question.
What special version of mediawiki is wikipedia running?
It is called 1.16wmf4. It's 1.16 with some additional changes.
And is it generally useful to use the development version of mediawiki instead of the official stable releases?

Depends if you want to be on the bleeding edge or not. You get all new features and fixes, but you get also affected by the new bugs, so although they are usually fixed quite fast, you need to be aware of that (and report them whenever you find them, of course).
