Are DC-9's becoming unsafe? I have heard that Northwest's DC-9's are very old.

An aircraft doesn't just become unsafe suddenly. I should hope that Northwest's DC-9s have been maintained well and are therefore just as safe as any. Finnair's DC-9 fleet for example averages an age of 20 years, which is not very old at all. So not even all DC-9s are "old" yet.

Northwest has spent a TON of money totally re-doing their DC-9's because the money spent on re-doing them was less than buying new planes. So, they should be pretty safe for a while

What types of work that they "re-do" on the DC-9's on Northwest Airlines?

Normally the types of "re-do"'s AF777 is mentioning, are when aircraft are due for a "D" check. This is one of the most thorough checks on an aircraft. As some of you might be familiar, the whole aircraft is stripped down; interior, wiring, various actuators, flaps, slats, name it! The only thing remaining is the basic airframe. After disassembly, they install new wiring, sometimes new avionics..etc. This is a "re-do".
The only thing that remains old is the airframe, which with careful maintenance is perfectly safe.
