[Ian McColgin]

Your questions indicate the need for a good, professional survey. One fears answering based on such scant information.

In general and unless after survey there's good reason to replace a major part of the rig anyway, you're best off setting her up as most recently rigged, spars matching stays and sails. Run her for a year that way before deciding if changing the mast is a good idea.

Why was the wooden mast included? Is it some old bit of original rig from which a later owner departed? Why is the aluminum spar shorter? It could be as simple as that rerigger could get the spar cheap? Which mast and boom do the sails fit?

I hope you've had a surveyor to give some direction on what looks to be a pretty big rebuild. If that surveyor is not qualified to inspect the rig and offer competant thoughts on spar choise, stay and hardware upgrades, etc., then find a surveyor, rigger, sailmaker or naval architect who is up for that part of the job.

G'luck
