I am probably being a little overly paranoid, but I just want to check on how to use the additional 2GB of disk space that was so graciously given to us.

I am assuming that you just shutdown the server, and click on the disk image that you want to add it to, and add the value to the new size input. Is that correct?

Like I said I am paranoid that I will screw everything up, so I would rather look like the fool now, than risk being one later.

Thanks

Yes. Shutdown your linode in the Web console, edit the disk image you want to resize and enter the new size in the 'New Size' field. After you click 'Save changes' the disk will be resized. When the task has been completed you should be able to power your linode back on and have the additional capacity.
