Geek help: static IP addresses

ciphergothQuick geek help sought with making sure I understand IP routing properly.
Zen have allocated me the static IP address block 82.68.129.72/29. Of these eight addresses, one is the network address, one is the broadcast address.
I've fitted an ADSL card to my main PC, saltationism. So it has two interfaces: an ADSL interface and a LAN one. That's two more addresses taken. So there are four left: I can give up to four more machines on the LAN static IP addresses.
The thing that worries me is that if the subnet for the LAN is 82.68.129.72/29, then can I assign an address from that subnet to the ADSL card? If I do, will my LAN be able to route to that address? If not, what should I do instead?

You need an IP address for your router/gateway as well, or is that what you mean by ADSL card?
