Use a lightweight line for sheets, 1/4 or 5/16. Use snap hooks to connect to clew, rather than tying on as you would an upwind sail. On my gennaker the clew's cringle size restricted my "fat" vinyl sheet shackles, so I attached a two foot pendant to the clew with a 4-5 inch bowline loop to make it easier to clip on. The sheets should reach back as far aft as possible before turning back forward to the winch or cleat you want to use. You can most likely tie a small block to your pushpit or stanchion base for this. If you want you can also create a pair of "twings" to give you more sheet control options. Google that to see what I mean. They are sometimes called "tweakers"
I'm not sure what you mean by an uphaul for a cruising spinnaker. You will need a spinnaker halyard that allows the sail to float outside the rigging, which means you'll need to fix a block to the mast just above the forestay connection and a horn cleat lower down to anchor it.
Besides the sheets and halyard, you'll want a connection for the tack.... these sails often come from the manufacturer with simple line attached to the tack that you would tie to the pulpit or tack fitting. The majority of sailors will build an adjustable tackline..... that runs back to the cockpit... so you can make adjustments to the luff of the sail.... maybe this is what you mean by an uphaul... You can attach a small block to the stem fitting for this. The tackline will have a simple shackle/hook for sail attachment, then down through the stemhead block before running aft to your desired cleat.
Once this is set up you will be ready to go.... all you need to do now is get the sail on deck in its bag, make the connections to sheets, halyard and tackline and you're ready to launch.
If you google search, "how to rig and sail a gennaker" you'll probably get a Youtube vid that will make more sense than this piece. ... Good luck, have fun.
