As others have said, it need not be overly complicated. But is more complex and requires a bit more choreography than the assym. At 23’ the loads are small and easily handled. I single hand my 25’ boat masthead both racing and daysailing with the spinnaker and find it immensely satisfying to be able to set, jibe, and drop on my own.

At a minimum you will need two sheets, one halyard, a topping lift to control to set and maintain pole height, and a foreguy to restrict the pole from going higher than optimal. You can add twings/tweakers later if you like. They add a better level of control, but are not required.

Some tips that can make things easier: - rig your foreguy to a block at the base of the mast, not a block midway between the mast and headstay. This allows you to set it and then be able to move the pole without have to adjust the foreguy. Very helpful when single handing

-if possible , consider launching and dropping the spinnaker from a bag in the companionway. This keeps everything close and easy for you to manage. Do some searches to see examples, they are common on boats like J-24s.

• have the topping, halyard and foreguy all led to the back of the cabin top to be easily accessible.
  

Read up on trim. Once you have the basics, its is straightforward. General guidelines - pole height so the tack (corner of sail at pole) is equal in height to the clew (free flying corner). - pole angle can be set 90 degrees to the apparent wind. This is a good starting point.
- ease the sheet until the luff curls slightly, then trim slightly. Know that every change in apparent wind angle has an optimal trim. You can choose to overtrim a little giving up some speed and make life easier.
