Yeah, they're essentially the same. 10 connections on the workstation... more on the server. Those services are only running if you choose to install them for the most part. Don't make the machine a PDC or BDC and you really won't have to worry about it that much. After install, check the services control panel and turn off whatever you don't need. That's the easiest way to make sure those extra things aren't running if you are really concerned about it.
Drivers should work the same for both under most circumstances. If all your stuff has drivers for Win2k, I'd consider that as well. Either way, if you don't really need the server parts of NT Server, there's no benefit that I can think of using it over Workstation. BTW, you can check the HCL on the install CD, but also check Microsoft's website for the latest update. The latest NT4.0 install CD probably has an HCL that is at least 2 years old and lots of stuff could have been added since then.
