Don't waste your money on a sock or a tacker. You don't need it on a 22 ft boat. You can launch and retrieve from the cockpit or by the mast and you don't really need to clip the sail's tack to the headstay. Not sure what you mean by a "conventional" spinnaker. It sounds like you need to do more research on the difference between an asymmetrical and a symmetrical spinnaker.... certainly you need to know this before you purchase unneeded gear.
Anyway, the sock and tacker were designed to assist short handed crew on larger boats, say over 30ft, for asymmetrical (cruising) spinnakers. You wouldn't use either with the pole equipped chute.
If you check YouTube for spinnaker videos, you'll see smaller boats do not use the sock. What works really well on small boats, especially racing dinghies and beach cats, is a "launch tube" but you'll want to learn the basics before you try to understand that very cool device.
FYI... rigging you'll need for an asymmetrical spin (cruising) Spin halyard with block at top in front of headstay, an adjustable tack line, two lightweight sheets (2x boat length) two turning blocks attached as far aft as possible, a pair of "twings" or "tweaker" (they're like floating jib leads), a turtle bag.
rigging you'll need for the symmetrical spinnaker: Spin halyard, 1 Spinnaker pole (equal to foredeck length), 2 sheets (1.5 BL) with collars to keep from jamming in pole end, 2 after guys (optional), topping lift, fore guy, mast ring connection for pole, two turning blocks, possibly two small winches, a turtle bag.
So...do your research and determine the type of spinnaker you want, then sift through the many YT vids on how to use it.... Finally, I highly recommend investing in a quality tiller pilot if you're planning to do much single handing.
