Windows 98 Second Edition and up also do a simple form of #3, aka NAT 
(Network Address Translation, where one IP address is shared by all of the 
computers on your network) & DHCP (which handles the provision & 
distribution of the local IP addresses for your local network computers, so 
that you don't have to configure the IP address, gateway, etc, yourself), 
when "Internet Connection Sharing" is enabled.  The standard configuration 
with it is fairly easy to set up and use, but making changes to the typical 
configuration (which is rarely required in the average home environment) 
requires changes to your registry.  You could alternately have a UNIX box 
as your firewall, running natd.  It all depends on your level of technical 
expertise.  I would imagine that there are some good tutorials out there 
for "Internet Connection Sharing" with Windows, a quick consultation with 
your favorite search engine should help guide the way.

As mentioned, there are some good products out there that will act as both 
a network hub and router, and the price on these is falling all the 
time.  Last I saw was a 10Mbps hub with built in router, DHCP server, & 
firewall, from Linksys, for about the same price as their 100Mbps 
switch.  I believe it was sub-$200 Canadian, which would be in the $100-150 
range US.
