Just to provide you with our experiences since 14 months ago. We started a system modernization program to build mobile banking applications using zLinux on zVM with services and data been served by the legacy IBM mainframe CICS system. I am the architect oversee the mainframe (zVM & zOS) infrastructure. From the 14 months and ongoing experiences that I've seen, it is absolutely important to not only have someone who is good at Linux but also have extensive knowledge in zVM. In general junior Linux system or very good high school graduate Linux guru are lack of "Enterprise" IT mind. Also, strong knowledge in network/TCPIP/vSwitches/hipersocket are also helpful.
I'll be glad to share our experience with anyone who is thinking of going down this route.

I for one am relishing the experience of getting to learn an environment that is entirely new to me. In answer to your question, I do think that you'd need a mainframe guy when getting started if your knowledge/experience is only from the distributed world, yes.
