Let's get down to basics. You didn't say what sort of spokes these
are, type and diameter(s) and how many miles they have served. That
would clarify whether to use them again or not.
As for length, lay the new rim next to the old just for comparison and
if they are close, the spoke length should work. Do not unspoke the
wheels if you plan to reuse the spokes, but rather transfer them from
the old rim to the new, one at a time, making sure to have a drop of
oil on each spoke eyelet in the new rim. Unlubricated spoke nipple
seats is what ruined spoke wrenches because it was believed that
torque arose from thread friction. This is untrue. Spoke nipples
become rounded when the spoke nipple seizes in the rim.
Aside from that, I suggest you get some new DT or Sapim 1.8-1.6mm
thick spokes after measuring the OD of the rim to get its ERD
(Effective Rim Diameter) then measuring from the OD of the rim down
to an inserted spoke nipple. Use a spoke calculating program on the
web to arrive at spoke length.
