I forgot a FROM clause, and you might want to add a
ORDER BY clause, if that is important:

select part,mfg,
       sum(CASE WHEN eta is NULL then qty ELSE 0 END) as qty,
       sum(CASE WHEN eta is NULL then 0 ELSE qty END) as "qty incoming",
       max(price) as "highest price",
       min(eta) as eta
from thetable
group by part,mfg
order by part,mfg;
