To give a quick reply, here's what I've found so far, regarding a clothes drive:

Donations urgently needed
PHUKET: As the island continues its recovery from the tsunami that hit the island on Sunday morning, many hospitals and other organizations are calling for donations to assist victims.
Hospitals: clothes, shoes, counseling:
Wachira Phuket Hospital and other hospitals say there is an urgent need for shoes, shorts and T-shirts, especially in sizes large enough for foreigners.
Shoes are the priority right now. Many of the Thais and foreigners who were hit by the wave lost their shoes, with the result that many have foot injuries from walking or running on broken glass and other sharp objects.
Stores in Phuket have given many pairs of shoes, but most of these are in sizes suitable only for smaller people.
Any footwear large enough for foreigners is welcome; even rubber flip-flops would be a great help.
Many people have lost all or most of their clothes and need T-shirts or shorts to get by for a few days.
Donations may be taken direct to any of the major hospitals: Wachira Phuket, Phuket International; Patong Hospital; Mission Hospital; Bangkok Phuket Hospital.
Many victims are still walking around in a daze and; some have lost love ones or do not know where they are. Any person with the time to go to the hospitals and help is asked to do so. In some cases just hearing a calm voice amid the confusion can help.
I'll see if I can find some more, especially for Sri Lanka, Indonesia & India.
