In stainless steel 6.0 and 6.1 (and gracul's unofficial 6.2 patch) unit recruitment is handled differently than you describe. Units are available across all ages, some being unlocked at certain times or from certain levels of barracks, stable, or archery range, but none ever being removed entirely. Sometimes recruitment pools are reduced (the maximum ammount of units available for recruitment), but this is minor.
However, in the RR (real recruitment) / RC (real combat) Compilation or sub mod, this has been changed, for historical accuracy. If you have anything RR/RC, the rules change a bit. Generally for this you have 2 major eras, the old and the new. The new era begins around 1300 and overhauls all faction's recruitment regardless of settlement size, while some old era units will remain, many are replaced, and the entire roster is different.
Also, yes, allied forces (either your own or from a friendly faction that is allied to you) will appear on the battlemap on your side if they are within the radius i described previously. This also applies to the enemy, so watch out for enemy stacks bunching up. To allow friendly armies to aid you, you need only check a tickbox next to whomever is commanding them in the pre-battle scroll (the scroll you see just before entering the battle-map).
As for upkeep, taxes can be adjusted to make the difference. Also cancelling construction efforts, and utilizing merchants and the like can help generate spare change. Honestly though this is largely unnecessary. Just be sure not to over-recruit, and you should be fine.
