The locking mechanism is more important for mbox mailspools, but 
dovecot has some extra files (.subscriptions and .customflags) that 
need locking as well. For the separate mails in the mailboxes dovecot 
needs no locking when you use maildir.

Index files on the local drive are a good idea if you only use one 
machine for the mailbox, if you use multiple, your index files might 
get corrupted. You can use in-memory indexes as well.
