Unfortunately, event handlers  are scoped at the SPWeb level. There are
two ways I know of to handle this.

1. In the FeatureActivated event, apply the event  handlers to the
appropriate lists. I don't have sample code to show this.

2. Code the event handler  and execute code based on which list (or
document library) it occurred to. Here's an example of the ItemAdded
event:

public override void ItemAdding(SPItemEventProperties properties)
{
base.ItemAdding(properties);

// Prevent the accidental triggering of events  from logic
executed in this method.
this.DisableEventFiring();

// Get the List Name in which this event was triggered.
string strListName = properties.ListTitle;

try
{
switch (strListName)
{
case "Courses": this.ItemAddingCourses(properties);
break;
case "Course Category":
this.ItemAddingCourseCategory(properties); break;
default: break;
}
}
catch (Exception ex)
{
properties.ErrorMessage = ex.Message + " " +
ex.StackTrace;
properties.Cancel = true;
}


// Re-Enable event trigggering
this.EnableEventFiring();
}

You can associate an event  to a specific  list, see this:
