Ed,
You can use the following system stored procedures to determine what tables
are FT Indexed:

sp_help_fulltext_tables

You can also use the following metadata function to gather more FT info:

select
ObjectProperty(object_id(N'<table_name>'),N'TableHasActiveFulltextIndex')
select
objectproperty(object_id(N'<table_name>'),N'TableFulltextChangeTrackingOn')
select
objectproperty(object_id(N'<table_name>'),N'TableFullTextBackgroundUpdateInd
exOn')
select
objectproperty(object_id(N'<table_name>'),N'TableFullTextPopulateStatus')

Regards,
John
