Whether you want a precondition limiting application of the router to
local domains depends on whether you've configured Exim with a notion of
local domains that matches the domains of email addresses available from
your pgsql_sys_aliases lookup. :-)
If you have a
domainlist local_domains = ...
in your main configuration section that specifies the same set of local
domains as should be handled by pgsql_sys_aliases, then yes.
If not, then no. But I'd give serious consideration to implementing a
sane local_domains domainlist, since it's used in several places in the
default configuration, including the ACLs.

Nope. Don't confuse routing with address verification. From and/or
sender addresses are rewritten by rules in the rewrite secion of the
configuration (empty by default). Exim (usually?) doesn't use sender
addresses to route messages.
