It does but it's not shown has E-stop and is just an input. Any input can be used for E-stop and just setup in control software to watch this pin.

Yep buy a 24V and use it to power relays etc that you'll need to safely control other things like vacuums or spindles, coffee machine etc

1) Looks like a reasonable kit for starting with, and should be more than up to the job you're asking.
