It might be  absolutely critical, don't know. I've never dried 
the ribs. They've always  gone on at whatever the shop 
atmosphere at the time supplied with nary an  indication of a problem
  Dittos. Sometimes they do, sometimes they don't.   No opinion as to better 
whatever.
 they don't

Incidentally, even if they expanded more along the grain than 
they  do, would it matter in an RC&S board. For that matter, 
shouldn't the  ribs in CC assemblies be brought up to very high 
MC levels before  assembly, to enhance the compression as 
everything  equalibriates?
  Seems right
