You'll also need a small heater, and an airstone is a good idea when using meds. Q tanks are best run as bare bottom jobs, easier to keep clean and less chance of any nasties remaining behind after treatment. Plastic plants are easier to sterilise if things do get nasty, and provide some cover for nervous newcomers.
Filter set-ups as descibed above, but be aware of the possibility of cross contamination when returned to the main tank. (And for the record, cycle bacteria die when dried out, so yes, they have to be kept running in the main tank)
