You can't update the drivers and BIOS until the mobo is installed. Either get an anti static strap or make sure you ground your self, touch metal, before you touch any of the parts. Use the exact number of offsets, no more or no less, and that there is a screw for each. Follow the directions and take your time. And once it's up and running offer beer to the computer gods. If you're too young to drink, let me know and I'll volunteer.
You should be fine
