Hi,
DCS World is indeed an amazing simulation. You can spend hour upon hour just learning each aircraft's systems and then refining the use of those systems using tutorials, quick start missions, single player missions and campaigns. It definitlely has the most realistic representations of any sim I have ever used.
I will try to answer your questions:

NTTR Region

There is also an upcoming Normandy map which will be the new terrain for a WW2 theatre.
For more info on all of these you can search or browse the forums at the DCS World site.

Yes. The DCS World forums. Same links as above. You will need to register for the forums separately from the DCS World shop.

Again, just have a look at the DCS World forums and you will find heaps. There are some great guides that have been created by a user for most or all of the modules. Do a search for "Chuck's" and you will see a heap of results for guides such as "Chuck's UH-1H Huey Guide". The User Interface itself is pretty simple to use, and any modules you purchase are added to your simulation automatically, so all you need to do is enter an activation code the first time you use a new product. The layout is very easy to use.

This has become an important point recently, as it has been discovered that there are sites that have been selling second hand keys. I have always purchased directly from the DCS World site, and I would suggest doing the same.

There are other legitimate sales points such as Steam, but I have heard of conflicts between the regular DCS base and the Steam version and it's modules. Just stick to buying direct from the DCS World site and you won't have any troubles.
Enjoy the sim!
Cheers,
