Hey Stanley,
Glad I could help. Hopefully this will take you a bit further. The link I've attached is for a MSWord document but has some good pictures. I think his main sail rig is similar to the parts you have. Most Hobie 16's use a more modernized 6:1 pulley system for the main sail. It makes hauling in that big sail in strong wind much easier. Leverage you know. The number of pulleys in a rig determine it's ratio.
The block /pulley/ that attaches to the boom would have three pulleys /sheaves/ and the block that attaches to the sliding car /traveler/ on the back frame would have three pulleys /sheaves/. The hardware in you pick is most likely parts of the original Hobie 16 rigging. I believe it would 4:1. The document link will help you rig that up. This doc also has the jib setup and rudder configurations.
One important thing. I don't know how old your boat is so I think it's very important that before you take her out you inspect all the cables /shrouds/. Look for any frayed wires in the cables. Make sure that the rivets that hold the frame and mast hardware are tight and clean. Safety is important. You don't want the boat falling apart on you when you sail.
If you want to send a private message with more questions please do so.
