Selecting Records from 125 million record table to insert into smaller table

Question

Oracle 11g
I have a large table of 125 million records - t3_universe.  This table never gets updated or altered once loaded,  but holds data that we receive from a lead company.
I need to select records from this large table that fit certain demographic criteria and insert those into a smaller table - T3_Leads -  that will be updated with regard to when the lead is mailed and for other relevant information.
My question is what is the best (fastest) approach to select records from this 125 million record table to insert into the smaller table.  I have tried a variety of things - views, materialized views, direct insert into smaller table...I think I am probably missing other approaches.
My current attempt has been to create a View using the query that selects the records as shown below.  Then use a second query that inserts into T3_Leads from this View V_Market.  This is very slow. Can I just use an Insert Into T3_Leads with this query - it did not seem to work with the WITH clause?    My Index on the large table is t3_universe_composite and includes zip_code, address_key, household_key. 
CREATE VIEW V_Market  as
WITH got_pairs    AS  
     SELECT /*+ INDEX_FFS(t3_universe t3_universe_composite) */  l.zip_code, l.zip_plus_4, l.p1_givenname, l.surname, l.address, l.city, l.state, l.household_key, l.hh_type as l_hh_type, l.address_key, l.narrowband_income, l.p1_ms, l.p1_gender, l.p1_exact_age, l.p1_personkey, e.hh_type as filler_data, 1.p1_seq_no, l.p2_seq_no 
     ,      ROW_NUMBER () OVER ( PARTITION BY  l.address_key 
                                  ORDER BY      l.hh_verification_date  DESC 
                  ) AS r_num   
     FROM   t3_universe  e   
     JOIN   t3_universe  l  ON   
            l.address_key  = e.address_key
            AND l.zip_code = e.zip_code
          AND   l.p1_gender != e.p1_gender
             AND   l.household_key != e.household_key         
             AND  l.hh_verification_date  >= e.hh_verification_date 
  SELECT  * 
  FROM  got_pairs
  where l_hh_type !=1 and l_hh_type !=2 and filler_data != 1 and filler_data != 2 and zip_code in (select * from M_mansfield_02048) and p1_exact_age BETWEEN 25 and 70 and narrowband_income >= '8' and r_num = 1
Then
INSERT INTO T3_leads(zip, zip4, firstname, lastname, address, city, state, household_key, hh_type, address_key, income, relationship_status, gender, age, person_key, filler_data, p1_seq_no, p2_seq_no)
select zip_code, zip_plus_4, p1_givenname, surname, address, city, state, household_key, l_hh_type, address_key, narrowband_income, p1_ms, p1_gender, p1_exact_age, p1_personkey, filler_data, p1_seq_no, p2_seq_no
from V_Market;

I had no trouble creating the view exactly as you posted it.  However, be careful here:
and zip_code in (select * from M_mansfield_02048)
You should name the column explicitly rather than select *.  (do you really have separate tables for different zip codes?)
About the performance, it's hard to tell because you haven't posted anything we can use, like explain plans or traces but simply encapsulating your query into a view is not likely to make it any faster.
Depending on the size of the subset of rows you're selecting, the /*+ INDEX hint may be doing your more harm than good.
