5. Do almost all drives offer step and direction inputs ?

1/ DC Brushless and AC servo's have no brushes to wear, are generally lower inertia, have potentially higher max. rpm, and can disipate heat better due to the windings being wound on the stator.
2/ Mix and match is possible with DCBL and AC, but are much harder to match up due to different forms of commutation etc DCBL is the easier of the two.
3/ voltage rating of the amplifier can be higher and current should be at least equal.
4/ In most cases, yes, providing the current limit can be set accordingly.
5/ Not almost all, some, if analogue or digital, you will need a step/direction convertor, I believe there is one featured on the zone here.
