As soon as you do a "select...for update", it locks all of the targeted rows. You can do what you want with them after that. You can copy them into a pl/sql table etc. The locks are released when your session does a commit/rollback (implicit like with DDL or explict). The only reason you would want them in a pl/sql table is to avoid having to re-query them or if each row needed very specific processing which you could not do is pur sql statements. Pure sql statements are always preferable - try to avoid complexity where possible.
