Yes, thermal paste is absolutely necessary. Your stock HSF comes with thermal paste pre-applied. It's the gray patch on the bottom. If you still need thermal paste, I recommend MX-2.

Thermal paste is very important. You CPU will most likely overheat and burn out if you don't apply it. Your i5's stock paste/heatsink is fine. If you want to over clock I suggest a paste such as AS5 or ASMX2. Noctua also has some pretty good thermal pastes in my opinion.
