Is Project Server 2010 used for Project Portfolio Management? Yes. Is there more to the question? PPM is one of the primary uses of Project Server.
Can multiple Skills be assigned to a resource? Yes. A resource Enterprise Custom Field must be created that allows multiple values. The Custom Attributes section for a Skills field for Project Server 2010 is shown below. Once the field is created, when a resource is updated multiple skills may be selected by checking the box next to each desired skill.
Choose whether the field has a lookup table, a calculated formula, or neither.

I typically check the “Only allow codes with no subordinate values” option. And for skills I always check the “Use this field for matching generic resources option.
