Well it would be a good thing if you did upgrade the BIOS to the latest,
If you are getting it by itself without the heatsink, you would need thermal paste and cleaning alcohol to clean off the old paste and install the new paste so that the new CPU doesn't have cooling issues.
If you are getting it boxed with a cooler/heatsink then you don't need to do anything other than manual labor (changing CPU and heatsinks).
