OK, there should be 2 jam cleats on the mast. One is for the jib halyard (also call the jib downhaul), the other is for the main downhaul.
Here is the best pic I can find for the jib halyard:

Airborne's setup is not stock but it's close. The Factory setup for the jib halyard/downhaul is a 2:1 downhaul. On the front right of the main is a strap eye that you attach a couple of feet of 1/4" or 3/8" line to. On the end of the wire jib halyard should be a block, you put the line thought that block and down to the jam cleat on the front left side of the mast. You then coil the rest of the jib halyard and stow it (in the tramp pocket or on the tramp just behind the mast).
If you have a cleat on the bridle, there could have been a roller furler on the boat at one time. You can also run the line down the jib luff and cleat the jib halyard there if you prefer. They both work, and really you don't need a huge amount of downhaul(uphaul?) on the jib.
Referring to the same pic, you can see the downhaul for the main sail. You don't need a cleat for the main halyard because you have the hook at the top of the mast holding the main up. The line part of the halyard should be coiled and stowed after you raise the sail, the wire part can be attached to the strap eye about 3-4 feet up on the front of the mast.
A block with a becket and 2-3 feet of 1/4" line should be attached to the grommet at the bottom of the main sail luff. The line should be run down from the becket through the cheak block (inside the mast rotator wishbone) and back up through the block over to the right side of the mast. It is then cleated in the jam cleat there. In heavy air you can really reef on this downhaul to flatten your sail and depower. Unfortunately you can only depower so much unless you have swept back spreaders (most 5.2s have straight diamond wire spreaders).
