Answer 1

You can combine an INSERT with a SELECT statement, passing your values in the select statement.

Assuming you pass the values of the first two columns using parameters @a and @b you can write

INSERT INTO TABLE Table1 (Table1Col1, Table1Col2, Table1Col3, Table1Col4)
SELECT @a, @b, Table2Col1,Table2Col2
FROM Table2
WHERE ....
