"Entity ID" and "entity name" in the siteminder GUI , is this an arbitrary value ? or is this tied to any metadata or anything
Following explanation to entity id and entity name
Entity IDIdentifies the federation entity to a partner. The Entity ID is a universal identifier like a domain name. If the Entity ID represents a remote partner, this value must be unique. If the Entity ID represents a local partner, it can be reused on the same system. For example, if the Entity ID represents a local asserting party, this same ID can be used in more than one partnership.
An Entity ID that represents a remote partner can only belong to a single active partnership.
Examples: CompanyA:portal1; http://ca-idp.forwardinc.com
Entity NameNames the entity object in the policy store. The Entity Name must be a unique value. CA SiteMinder® uses the Entity Name internally to distinguish an entity at a particular site. This value is not used externally and the remote partner is not aware of this value.
Note: The Entity Name can be the same value as the Entity ID, but the value is never shared with any other entity at the site.
Value: An alphanumeric string
Hope this helps.

SungHoon_Kim has excellent article(s) about federation setup :
On this page he discusses those entries :
Here are his notes, EntityId was the important one here is how he described it :
EntityID is what you SP told you. Entity Name is what you want to call it.
And here are the Entries for the IDP & SP Entities Kim uses :
