It's not documented a lot but for example, Jumbo has a feature called 
"pot sync". If one process cracks a hash, the other processes will see 
that and stop wasting time on it. In case of salts (especially unique 
ones) this is a major benefit: When half the salts are cracked, speed 
will be twice as fast.

No, only one section is used. For LM hashes and a few others, the 
LM_ASCII section is used. For other formats, the ASCII one is used. This 
can be tweaked in john.conf, including using the UTF8 section when 

You can force use of whatever section you want using eg. -inc=utf8 or 
-inc=custom (if you built a custom.chr file). Try it out using -stdout 
and watch the difference.
