SP Things to do March 29 and 30 (São Paulo)

I have a quick two days in Sao Paulo before heading to Iguazu Falls. In order to make the most of my time there, can anyone provide a website of things going on around town that I can use to research? Preferably English but I'll pull out my Portuguese dictionary if I have to. I am not learning Portuguese as quickly as I had hoped, so I will be very grateful for some ideas on places with a good ex-pat crowd. My Hotel is near O'Malleys.so will probably check it out. Oh, And was wondering if people smoke in bars and restaurants there.

Obrigado
