I do not believe that a single "query" will give you what you want here.  YOU could have 3
seperate queries:
1 for customer detail by state.
1 for state total 
1 for grand total

However, if you use a reporting tool like crystal or others, they have the ability to generate
summaries exactly as you are referring to here.  you would only need to pass it the query on total
per customer.  The reporting utility has a groupby feature where it would group the customers by
state for your.  In the group by summary it would automaticly display state total.  Then if the
report footer you could add a grand total summary for all of the records you passed to the report.

The following link show some of the reporting programs that you can use.

Well, two queries one for the individual totals and one for the summary 
totals is good (maybe a third for the grand total), but you should do a 
union of the two and then play with the order by and/or group by clauses 
(depending on the data) to get the ordering that you want. I can't even 
count the times I've spent banging my head against the proverbial wall 
(you do have a proverbial wall don't you?) trying to get these kinds of 
queries to work with joins, sub-queries, case statements, etc... only to 
come back to using union on simple, to-the-point queries.
