How to pass and work with a PL/SQL or Temp table in a Procedure?

Question

My problem is that I have a query that involves about 10 tables or so, but everything starts from one base table. I am trying to split the base table so that the query actually finishes.
Problem Query:
with base_table as
select * from table_a
, t1 as
  select * from table_b
-- There are some manipulation in the SQL, but not listing it here.
, t2 as
  select * from table_c INNER JOIN t1 on t1.id = table_c.id
) What I want to do is limit base table and thus create a procedure such that it evalutes a temporary table and the temporary table will be limited by 1000 rows or so.
Thanks for your help.

Currently I am using:
DECLARE
   l_start                       NUMBER;
   l_increment                   NUMBER;
   l_max                         NUMBER;
BEGIN
   l_start := 1;
   l_increment := 100;
   SELECT COUNT(*) AS the_count
     INTO l_max
     FROM table_a;
   LOOP
   INSERT INTO new_table
     WITH base_table AS
     (SELECT p.*
        FROM (SELECT DENSE_RANK () OVER (ORDER BY alpha_id) rnum, a.*
                FROM table_a a) p
       WHERE rnum BETWEEN l_start AND l_start + l_increment - 1)
   , t1 AS
     (SELECT *
        FROM table_b
-- There are some manipulation in the SQL, but not listing it here.
   , t2 AS
     (SELECT *
        FROM table_c INNER JOIN t1 ON t1.ID = table_c.ID
SELECT *
  FROM t2, temp_base;
COMMIT;
      l_start := l_start + l_increment;
      EXIT WHEN l_start > l_max;
   END LOOP;Is it better to create a Temporary table or pass the data as a cursor:
SELECT DENSE_RANK () OVER (ORDER BY alpha_id) rnum, a.*
FROM table_a a
Thanks.
