Chess - rot and dry rot is cancer in the wood. it is hard to arrest once it gets going.
a hard blunt tool, such as a phillips head screwdriver, can find soft spots in the wood.
if found, then it is time to repair or replace the wood.
as for priming and painting: I suggest you always read, understand and follow the instructions
on the label of all products that you use. (Norm Abram said that).
scraping old paint "could be" hazardous: if it is old, old paint, it "could" contain lead.
so all chips must be contained on a dropcloth and disposed of accordingly.
and also, eye and respiratory protection must be used.
we are not there - we have no idea of the condition of the wood or the paint or age.
I strongly suggest you get in touch with a professional (licensed) painter and ask him/her to "donate"
some of their time to your project just in the advisory and educational field. not to do any work.
it will make your project go a lot smoother (and safer).
keep us in the loop.
there is no educational alternative to having a front row seat in the School of Hard Knocks.
