When cycling a tank with fish you are best off doing small frequent water changes. Once the tanks are cycled you can go back to larger weekly changes as normal maintainance.
Carbon doesn't filter bacteria out of the water. It deals with chemicals like meds and various trace elements. Adding gravel to your hospital tank will provide a larger bed of bacteria. When not in use keep this going by adding your own ammonia and it will be ready to go in an emergency.
No need to boil water for a water change unless you are getting it from a natural unchlorinated source.
Yes you can add the dechlor straight to the tank and then add the tap water. In this case dose for the volume of the tank rather than the volume of the water change.
Not sure about antibiotics since they are very hard to get hold of in the UK and I don't have any first or even second hand experience with them.
