I shall endeavor to provide dumb answers in return :^)  For *good* 
answers, a great place to start is the Handbook, 
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/index.html. In 
addition, I'm sure some of the many smart people on this list will speak 
up.

Also, notice that I've changed the subject line to reflect a hint of the 
message's content. This list is archived, and anyone searching later migh 
not know to use 'edification' as a search term.

When he says "shell terminal", think "command prompt". nc is netcat, but I 
didn't know Windows had that. In your friend's defense, I use Windows 
every day (at work) and I can't always remember what things are called. 
Especially since MS changes terminology every now and then, evidently just 
for the hell of it.

Yes. You can either set it up for dual boot - either by adding a second 
hard drive, or by partitioning your existing drive if there's space - or 
you can run another OS within a virtual machine of some sort. The latter 
would need a pretty fast machine if the guest OS is to have decent 
performance.

Having said that, I found it easier to get started using an old PC that 
was too slow to run a modern Windows, but perfectly fine for a GUI-free 
BSD. I'm typing this on an old Dell that I bought on ebay.

The server's admin would have to give you a shell account. Most commercial 
ISPs won't do that, but maybe your friend will.

Hope this helps, and welcome.
