Yes, article numbers aren't usually recycled (except if the active file
gets damaged or lost, then article numbers might get reused), leafnode
currently has no renumber utility or facility.

Looks like Reiner's suggestion - mind his caveats though :-)

You will if you run rsync rather than fetchnews.

No. Tool tip: "Unison" is a useful tool for such synchronization efforts
because it can detect on its own which way your files need to be
synchronized, so you don't have to remember which way you synchronized
the files the previous time. I'm not sure how useful (or speedy) it
would be for synchronizing the spool -- I'm not sure about its efficacy
for larger amounts of files.
