Answer 1

In this case your group condition is only the number ct_no. Then you must derive the correct sum for each column. One possibility is to use a case expression to restrict the sum to the appropriate rows.
The following code snipplet might give you an idea.
select ct_no,
       sum(case when due_date between TO_DATE('1-NOV-2007')    and  TO_DATE('1-NOV-2007')+30 then due_amt else 0 end) ovd_30,
       sum(case when due_date between TO_DATE('1-NOV-2007')+31 and  TO_DATE('1-NOV-2007')+60 then due_amt else 0 end) ovd_60
from le_dues
where ct_no=3000
and due_date between TO_DATE('1-NOV-2007' ) and  TO_DATE('1-NOV-2007')+30
group by ct_noI would also change a few other things in this code.
1) Use a date format mask
2) A date value has a time component. You would miss rows that are due on (01-Nov-2007 14:37) + 30
