Nothing.  It's the primary and secondary DNS servers that control how your
host is resolved, not your box.  As long as mybox has the IP address that and think it has, you should be good to

As Chris said, what comes in where will depend on what address it is sent
to.  What goes out where depends on a few things.  If you want to use one
interface to access a particular host or network, you can set up a route
accordingly.  If you want to access everything with both, you might be able
to put 2 default routes (i've seen it done but don't know if it works and
if it's supposed to work).  I saw you've been looking at bonding which
might also work, but I don't know about it.

Can I ask, why you have 2 NICs?  Is it just to get 2 addresses or are you
connected to 2 networks?
