Sadly, Haiti is already a poor to begin with. Never was a good infrastructure as in clean water, hospitals, medicine, antibiotics, food, etc...etc... Hell, you are extremely lucky if you had clean running water.
What it needs I think is air drops on clean bottled water alone. That would slow down the suffering. The country needs tons of medical personnel to treat the thousands wounded. There are a lot of lessons to be learned from Haiti. Sadly, with such a small time window to work with 1-2 weeks at best, even if you did donate money for a good cause I doubt it would go anywhere since the airport is jammed packed and no where to land. I think if an aircraft carrier makes it there that would be a big help.
I did find it pretty funny that they were saying former president Clinton was organizing air relief. Then after that one of the news casters said, maybe it would be a good opportunity for Bush Jr. I don't think he was much of a leader to begin with so... Hopefully he will just give money and lots of it.
