Most OEM installations give the user few choices. The advantage of OEM is that it will support all hardware in the computer whereas, as you've discovered, a generic retail package might not cover everything -- particularly if you have hardware designed after the install disk was generated. (Case in point: Retail Windows XP is a real pain to install if you have a SATA hard drive).
The only Windows XP usernames that can't (or at least shouldn't) be deleted are the built-in "Administrator" and "Guest". Apart from that, you can create, delete, or disable any user that you want simply by
Right-clicking "My Computer" -> Manage -> Local Users and Groups -> Users
and going from there. You may not be able to delete the user you're currently logged in as, but otherwise you can do what you want with your user list.

Go here:

and click on the link "How do I tell if my computer can run 64-bit Windows" link.
Personally, I would avoid 64-bit Windows XP as it was not around for long and there's not the big 64-bit driver support for XP as compared to Vista or Windows 7. Also, I don't believe you can even purchase XP at this point in time. Vista & Windows 7 might be a consideration depending on how much RAM your computer will support. However, if you find yourself purchasing additional RAM, you might find that for a few extra bucks you can buy a complete new computer.

IMHO, I'm not a big overclocking fan. Typically you only gain a 5 - 10% improvement (barely discernible) and you increase dramatically the problems of heat dissipation and memory access time margins -- basically eating away at reliability (which I consider more important).
