Not quite. Volunteer militia TrainUp to line infantry. Volunteer militia are only those units that actually state that they are volunteers on them.

With time in later years regulars train to late infantry (they do not havve a different name I just call them that). This represents the technological and tactical progress and the infantries get better stats.
This is not quite true, although the difference is small. Infantry elements can TechUpgrade to somewhat better units through events, but you cannot influence this and it has nothing to do with how long the unit has be in the field. In fact you are still building the same units in '61 as in '65, so the elements you buy in '65 will still have to TechUpgrade; the rate at which they do so in '65 is however higher IIRC.

You can see the star in the unit display info at the bottom. If you hower over it, it will show how much xp points you have and how much do you need to get a star.
I don't think the number of XP given has changed, but don't forget, every element with <Experience Leve 2 have a 75% chance at gaining 1XP per turn. So if you are monitoring units stacked with a "Training Driller"

you will likely see that they gain 2XP per turn.
Also the tool-tip tells you how many XP you need to gain the
NEXT EL (Experience Level). How many you need double for each subsequent level.

See my post above for a more concise description of this.

Again, see above.

I think the South can build a few of these, but not every states has them, and their number are pretty limited IIRC.
