Maybe you should try it first and experiment a bit. It's rather hard to
answer on vague questions.

As far as I understand your question: you can change the TOS based on the
incoming interface (and lots of other options). And I think it isn't
usefull to reset the TOS field when you send out the packets into the
internet, because most routers won't use the field and simply ignore it.
When a packets comes back, you should route it dependand on the
destination, not on the TOS field because that can be anything.

I hope I haven't told complete nonsense.
