So,

   Given the output below, is there any real benifit to compiling a custom 
kernel with an amd64 machine type (performance gains?), and given that 
this server will be a Web/Email/Mysql server?


you can trim out all the unused drivers to slim your kernel down, or there 
may be other kernel options you want to use that are not in the GENERIC 
kernel.


but for what you are using it for, there's no harm in just staying with the 
GENERIC kernel.

Understood,

Does the default "GENERIC" kernel see them as i386 or amd64 when
booting then?, or does using amd64 require a custom kernel?


The kernel and the rest of the system are compiled for i386 or amd64.
You can run amd64 software on amd64 architecture hardware, and you can
run i386 software on i386 or amd64 hardware.

amd64 for both CPU's to run full 64-bit version, otherwise i386 for 32-bit 
mode. ia64 is for Itanium CPU's only.

Note that some features and ports are only available with i386.
