I just went through this job over the winter and launched today. More verbiage and pictures of how our job went are here: 2011, November 30th. Begin drive train rebuild | Odalisque
My recommendation would be to check for excessive wear on you bronze shaft at the strut or stuffing box and if it is at all scored to just cut the shaft in half and get a new SS shaft made for your boat. A new SS shaft should cost around $200 +/- and with the shaft out it is easier to separate the prop from shaft and the shaft from coupling. You then have access to replace your Cutless bearing, if you want to, and your stuffing box packing.
Our old bronze shaft was scored by the Cutless bearing so we cut it in half with a Sawzall in no time. The Sawzall also came in handy for removing the old Cutless bearing but you can also use more gentle tools like a hack saw. Press fitting these things out doesn't always work out to be easy.
Have no fear though because you already have the threaded rod you need for pressing in the new Cutless bearing (and there is no other way to do that). One hint: box wrenches get much better torque.
