I would not like to do a job like that with the mast hanging of the crane..
Any small shift of weight or waves from a passing boat make this unpleasant.
If you have a keel stepped mast I would just have dropped the mast in place and slacked off the hoist. Using the halyards to position the masthead while measuring the wires.
I you have a deck stepped mast you need enough ropes to stay the mast temporarily.
fore and aft and side ways (4 in total) if you don't have 4 halyards you could tie some temporary stays to the mast head before raising the mast.
step the mast, put the temporary stays/shrouds in place, remove crane.
I have linked this before http://www.seldenmast.com/files/595-540-E.pdf
Edit:
You must raise the mast without the furlex installed
As for the sequence:
Cap shrouds (top shrouds)
Lower shrouds
Backstay
Forestay (headstay), take the stay down and assemble furler and install stay.
You must take the furling assembly into account when measuring the forestay
You can find the furlex documentation here
