|Restoring from a Dell Reinstallation CD isn't the best way to do this, as the hardware would be almost certainly completely different.|
You have two different issues. Make sure that the "Show Desktop icons" is set. As for the other issues, go to HP's website and see if you can download the drivers you need.
I'd recommend checking into obtaining a Restore/Reinstallation CD from them as well. Is it possible there is a Hidden Recovery Partition on this machine?
