select & group by

I've got a problem selecting some specific data from my table. Imagine
the following rows:

part | mfg | qty | price | eta
---------------------------------------
TEST1 ABC 10 100 (No ETA, as item is in stock)
TEST1 ABC 12 120 04/04
TEST2 CBA 17 10 05/05
TEST2 CBA 10 20 (No ETA, as item is in stock)

I'd like my selection to produce the following result:

part | mfg | qty | qty incoming | highest price | eta
-------------------------------------------------------------
TEST1 ABC 10 12 120 04/04
TEST2 CBA 10 17 20 05/05

Any clues on how to do this ? I kow the group by part, mfg, max(price) -
but I do not know how to deal with the splitting up qty and stock qty
and incoming qty.

Thanks.
