Look on www.europabarbarorum.com. There should be some maps there with names of provinces. Or you could put your cursor over the mini-map, ingame and it will tell you the province name. Or you could hold down the right mouse button on the strat map and it will give you the province name and terrain type you are currently over.

Those are the reform units in that MIC, you need to get the reform building before you can actually get them. (The 'why' about this, is so that reforms take less buildings and more can be implemented.)
