French Keyboard, €, metric and date with English speak W8

[metramo]

Living in France you cannot avoid a French keyboard, they're everywhere. So I learned using the azerty, but stuck to English.

This is of course beyond the people designing Windows.

So how can I have Windows 8 speaking English, but using French options for the rest (€, keyboard, date format, metric)?

And of course, ALSO WITH METRO please. It seems independent of the "real" OS.

Thanks in advance

A lot of these changes can be made through the Control Panel > Clock, Language and Region
If it affects Metro, I do not know.
