Where to define netmask, gateway and ip-address?

I managed to get familiar 0.4 running and connecting to our company's
fireless accesspoint by editing /etc/pcmcia/wireless.opts
and then giving following commands from shell

     ifconfig eth0 my-ip-address netmask 255.255.255.128 up
     route add -net my-network-address netmask 255.255.255.128 eth0
     route add default gw my-gateway-address eth0

I couldn't however figure out where I should put these commands if I want
to get system working out of the box after rebooting?
