I would use FreeBSD 9.1.  It has built in support for gpart (the default 
for the new installer) so it can handle disks larger than 2TB (which you 
will likely have) and has numerous improvements to the network stack as 
well as many of the network card drivers.

I can't answer the second question since I use the defaults, but there are 
pages on the internet describing how to turn the kernel for high speed 
network performance - like this one -
