Full Disclosure: I work for EMC Consulting that develops the Scrum for Team System process template.
The richer work item modelling available in TFS 2010 has enabled Scrum for Team System to support much more complex Scrum implementations ( http://microsoftpdc.com/Sessions/FT09 ), however, this does mean that the most straightforward scenario is more complicated to setup.
This was a principle reason for creating the Scrum Masters Workbench tool, as it provides a UI for visually configuring the artefacts you mention. Additionally, this tool has a 'Quick Setup Mode' whose main purpose is to make it quick and easy to setup the required artefacts for the straightforward Scrum scenario (i.e. a single team).
See http://consultingblogs.emc.com/crispinparker/archive/2009/11/27/scrum-for-team-system-v3-beta-2-scrum-masters-workbench.aspx for information on the Scrum Masters Workbench.
