Johnny, if your 5.7 has the tracks on the hull, you don't need much. You should have a little slider on each track that gets locked in place with a pullknob. You shackle the jib block to the strap eye on that little slider. If you get the standup springs, bonus, if not they're only 99 cents. The jib sheet then runs from becket up to the block near the jib clew, back through ratchet,across to opposite ratchet, up to clew block, & back to becket. It sounds way more complicated than it is.
You should have the block attached to the mast for raising the jib.
Here is the bridle, showing the tack hangar & shackle you attach the jib tack to. The wire on the left is the fore stay. The thin wire in the center is the jib halyard, the shackle that attaches to the head of the jib has been hooked to the tack shackle for convenience while in storage.
That 1st Ebay looks like it is only for 1 block, you need 2, & it is non ratchet. The second auction is a good deal, if it doesn't get bid up. Wait til 20 seconds before auction close & try for a deal, or buy HULLFLYERS, then it sounds like all you need is the jib sheet line. You can soak the blocks in clean water overnight if they are full of salt.
I have seen several pictures showing boats using various lengths of pigtail to clew block. The longer that line is, the less jib sheet you will need.
Sorry, I don't have a photo of my 5.7 rigged,(I'm up at the cottage now but don't have a camera or cell phone, I'll get one if you want a pic) here is the top end, mine uses a half wire half line halyard. Don't worry about rigging a 3:1 halyard, Nacra says for recreational sailing just stretch the wrinkles out.
Until you get the required hardware, just sail without the jib. It would be a PITA to use without any means to cleat, especially if you are solo.
I was solo today in 12-18 mph with no jib. As long as you have some speed it will come around every time. Solo, all your weight is at the rear when you flip the stik around the blocks. The bows will be clear of the water. They catch quite a bit of wind, & once through the eye they will pivot the boat quickly. If you blow it, well just point the rudders in the direction you want the stern to go & wait a few seconds. As the boat drifts back the stern will go where you want it.
Once you rig the jib, make sure you string a preventer (shock cord from one end of the DS rod upwards through the diamond wires, around the front of the mast, & across to the other side of the DS rod)so the jib blocks near the clew don't get hung up at the mast base every time you tack.
I'm pretty new to my 5.7, it's a handful in over 15 mph, I can't get full speed out of it then because I lack the weight to hold it down when I power up. I'm not trapping out solo til I get a bit more experience, or have somebody else around in case rescue is needed. It's pretty quiet here during the week.
