The licence is just to indicate back to microsoft that you have bought and installed a legit copy of XP. They have holograms on media and those little stickers, all supposed to be hard to copy by forgers.
After the install completes and you fire up windows update, one of the programs that is installed is WGA (Windows Genuine Advantage). It attempts to detect if you're running a cracked version of XP or are using any of the mass licence keys that they know are compromised.
If you're not that worried about the legality of it, you probably will be able to install your existing media and key. I believe there's a small number of allowed re-installs before authorisation starts acting up (Anyone know how many ??) Being behind a NAT router should keep you safe while your install & patching is taking place. The installed licence won't match up with the 98 licence on the case, but there's nothing physical to block the install.
The vendor probably asked about licences because he had already paid MS for the 98 OEM licence and it works out cheaper to buy a 98-> XP upgrade on top rather than a whole new XP licence.

Nahh, I'm sure we've got to the bottom of it nowI'm sure that makes no sense.
