Trust Server 2003 to Server 2008

We currently have one domain, running a few 2008 Domain Controllers, and few 2003 Domain Controllers. Our currently domain level is 2003. Currently our Domain functional level is 2003.
We have a new project that we want to deploy in the DMZ to offer services to some outside entities. The application will require a domain in our DMZ, an Application Server and SQL Server. Users from outside all organization will connect to this DMZ via connectivity we provide. They have their own domains we don’t want to trust those domains and will use credential we create in the DMZ. Our internal users may eventually need to access the services in the DMZ using their internal credentials. My question is if we want to allow our internal users to access the services in the DMZ and outside entities to access the dmz using credentials we create on the domain in the dmz. Would that not be a Create a One-Way, Outgoing, Forest?
Can we deploy Server 2008 Domain controller in DMZ, since we are not yet 2008 Domain/or functional level in our internal domain?

A1. Yes, It would be out-going trust from DMZ forest to Internal forest.

A2. Yes you can, trust can be established between WS08 DC and WS03 DC. Your internal domain/forest functional level doesn't need to be 2008 for this to work.

Hope that helps.
