1. In k3b, go to Tools menu, then select 'Write to bin/cue file"; you need a .cue file to burn a .bin file.
2. You have to set up NAT (network address translation) firewall script on your linux box, using iptables and ip masquerading to route the network traffic from your windows box through your linux box. Make sure that you edit the /etc/resolv.conf file on your linux box to include the address of your ISP's DNS server.
Here is the section from the Red Hat manual on firewalls and NAT:

You can also search linuxquestions.org or google for 'iptables masquerading red hat'
However, if you want to avoid configuring iptables by hand, you can try a GUI iptables firewall building tool:

Alternatively, install Mandrake instead of Red Hat. Red Hat is actually not that newbie-friendly. Mandrake has a GUI control centre similar to Window's Control Panel. Mandrake has an Internet Connection Sharing wizard. Here is the section from the online Mandrake manual:

Once you've set up your linux box, then you need to make sure that your Windows network settings are correct. Under TCP/IP properties, add your ISP's DNS server address in your Network setup. You may need to enter your linux box's IP address as your gateway address.
