upgrade the RAM snow leopard
I am thinking to upgrade RAM from 2GB to 4GB 1067 DDR3. Any advice?

Welcome to the Apple Support Communities
First, check if that's the correct type of memory for the MacBook you are using > http://support.apple.com/kb/HT1651?viewlocale=en_US&locale=en_US Apart from that, you can also see the steps you have to follow to install memory.
Then, you can buy the memory in OWC or Crucial. I recommend one of these providers because their memory is compatible with Macs, but there are different brands that have supported RAM
