IBM (yes, IBM) actually has a redbook on this and how to
use TS & Citrix.
I don't know the address of where to get it but the title
is "Implementing Windows 2000 Terminal Services and Citrix
MetaFrame on IBM Netfinity Servers" It also includes how
to install a variety of softare including Lotus Notes
v5.x, Office, Client Access.
I just emailed (or attempted to) it to you.
