Firstly: if you have several questions, could you next time please split them into individual paragraphs and number them?

Then to answer your questions:

1.) Artillery: depends on what you want to do with it. Those 10 cm guns have a good range, which is handy for counter-battery fire (or for avoiding enemy counter-battery fire). Against on-map targets it is decent, but if you want something that packs more punch you might want to try 15 cm battery instead (higher HE kill, HE penetration and warhead ratings).

2.) Aircraft: these are not allowed in the core. Air forces tend to be organisationally quite distant from the typical ground forces you see in Steel Panthers. It is already a stretch enough that you can have corps level artillery assets in the core.

3.) New units: there is no separate entry for the "new this month" units. So you will need to scan the lists yourself to find what is new. Familiarise yourself with the in-game encyclopedia if you want to know when particular units become available.

4.) Moves left: actually this is displayed in the units menu - there you can see a table of all of your units and a number displaying how many moves each one has left.
