Answer 1

What will Harmony mean for me as a programmer?

More options

I have various JavaScript programs... will I have to re-write these?

No

How should I get ready for it?

At the moment, there really isn't much you can do beyond the usual "becoming a better programmer in general".

Can I already begin programming against Harmony?

Not practically. Chrome, at least, has some features implemented (but not in such a way that you can use them on the WWW).

When will it be released?

Possibly by the end of 2013, but it will be longer before there is widespread support in the browsers on people's computers.
