Do I continue to attach the nylon jib hank onto the forestay or do I hoist the jib completely independent of the forestay?
Yes, absolutely.

If the latter, will the Aussie jib tension the rig or do I need to snug up my shroud wires?
The Aussie halyard tensions the rig. You do not need to adjust your shroud wires.
The major benefit of the Aussie halyard is that the tension on the line coming down the mast is 1/3 of the tension on the wire in the original system. Since the line is typically cleated off on the side of the mast, this reduces the tendency of the jib halyard to rotate the mast on its own.
On new boats, the lower turning block is on the front of the mast - that completely eliminates the jib halyard's influence on mast rotation.
