Great boats, all the Nacra skeg models. Can I suggest you make an album, & add all your photos there? Use the FAQ section, up in the top menu for how to.
I can’t speak specifically to the newer 5.7, but quite a bit is common to the older ones.
My jib (5.7 & 5.0), were rigged same as yours, a shackle at the top, with a combination wire/line. Only difference was the wire block was hung directly on the mast. Remember, you don’t need to pull the jib piano wire tight! For most sailing, just pull the wrinkles out, & maybe a little more. I changed out the wire block/wire halyard to a single line of Spyderline, & a tiny block.
I just pull & cleat, to a clam cleat I tied onto the forestay adjuster, as my Cats stay mast up on modified Seadoo lifts. If it’s a high tech line, you don’t need it very thick.
I don’t believe that ring at the forestry adjuster is for the spin pole, at least not the way it’s currently rigged. That setup would force the pole against the 10 hole adjuster, quickly wearing it.
It might serve a dual purpose. To tack the jib, & have the halyard come back down the forestay, ( inside the zipper), then through the ring & back to the front beam. This would allow changing jib tension on the fly. This is how you have to rig it if you have furling jib. I don’t think those Mylar sail like to be furled, & of course you would have the drum/swivel...unless a previous owner kept those parts, that might explain the extra pigtail up near the mast hound.
Here is how I rigged the jib, using the wire block. Note the small eye strap on the mast, that was where the wire block attached before converting to furling.

Here is how I used a Portuguese turnbuckle, (as MN3 mentioned), to tension the rig. A few turns of slippery line makes it easy to obtain good tension, then just tie off.
DON’T let anyone else touch this line, unless you have a safety, they will end up dropping the mast!
If you are solo, it’s easier than hanging on a trap line, & trying to remove/insert pins. If you do use that method, I strongly suggest keeping a small screwdriver with you. At some point you WILL drop the damned pin, not be able to reach it while hooked onto the trap.
The little clam cleat is to tension the jib. I simply pull the halyard to desired tension, then lock it in the cleat, reverse at days end to slacken the jib. (My jibs stay up all season).

Bear with me if you already know this. Be ABSOLUTELY SURE to keep the mast rotated 90* while stepping or lowering. If not, you will break the mast base. This photo shows why. If you drop the mast from this position,(not rotated), the base will snap, or you bend the DS rod.

After the mast is up, remove the pin, rig tension will keep the mast on the base. When you do drop the mast, think about which way you want to rotate it, so you don’t end up like this. It was the end of the season, I was solo. Ended up cutting the bolt vs raising the mast again. You can use any 1/4” bolt, pin or screwdriver.

Lastly, make sure the mast is sealed! Up at the top, rivets on hound & diamond wire tangs, rivets at bottom, & the base. The 5.7 will float very nicely on its side, the mast will only sink to about the hound, as long as you get off the boat immediately. Solo, you will probably need a bag to right, unless the wind is 20mph, then it will come up solo with a good plank technique. They are great boats, carry 3 easily, & are fast, you really have to be ham fisted to pitchpole it. When pointing, get the weight up front, sink the windward bow down.
Sorry I can’t be of more help with rigging. It is difficult to vision your entire setup from seeing only the bits at end of lines. I would raise the mast, with help, then much of it will make sense as you see what your dealing with.
