Re-installing XP again from scratch. Which sequence to follow?

I'll have to install a new copy of XP and seek help with the right sequence to follow.

The matter is that for a reason I'm unaware of my current XP installation is no longer eligible for patches, updates, etc. It become clear just now that I tried to get SP3 from Microsoft. It seems the shop I bought the PC from had installed the same XP license on several machines. Of course these guys have vanished from Earth's face at the time I returned to the shop to complain.

So, what I did was to buy a brand new copy of XP Pro (in a retail box) and now I'm going to install it in a second & bigger HD. After that I'll try to move every settings / applications / data from the "old" HD into the new one. As it isn't a new PC, both HDs will be running at the same time on the same machine, like a dual boot machine. Once the "new" installation is as close as possible the current one the "old" HD will be re-formated to become data storage.

The sequence I referred to earlier as help needed is regarding with one came first of each other considering the following :

monitor's driver installation - video card's drivers installation - external sound's card installation - wireless router - printer - wireless mouse & keyboard - setting up Internet connection - Norton Internet Security 2008 -

Regarding the current settings currently in use I plan to use XP utility FAST - File and Settings Transfer - wizard to do the transfer.

Would the sequence above be the right one to take? Any suggestion about a strategy to accomplish the task are more than welcome.

Many thanks.

well, this is something I'm not aware of. Once I do a XP clean install on new HD do I have to install Mainboard chipset drivers? How do I do that?
