Joe, It's not really _IF_ ISTG is running - it is. It is a role that the KCC assigns and requires, and unlike the Bridgehead, you cannot control who the ISTG role holder is.
As to costing - the cost is assigned to the link. The site link is created by you and creates the physical connection to AD that is already assumed by the KCC. It defines the protocol (RPC or SMTP) and the costing based on relative speed of other site links in your infrastructure. The KCC manages the connection objects - the replication topology will take into account the costing you have placed on your links - whenever possible. The lower cost will be favored over a higher cost when creating the connection objects. Site links - created and costed by you. Connection objects - created by KCC, and infulenced by site link costing. ISTG (Intersite Topology Generator) - with the KCC, creates and maintains the replication topology. HTH!

Does the ISTG handle all of this on its own, or does it consider link costs when it creates its replication model?
