BT Home Hub WDS a few questions

I'm going to be helping someone who has just got BT Broadband and Home Hub installed. We want to install a PC in another room and can't lay cable so will use wireless. PC doesn't have a wireless card, and I have a spare wireless router (Linksys WRT54GL) so we'll use that.

Plan to set up a WDS link between the Home Hub and Linksys, then wire the PC to Linksys.

A few questions. Apologies if obvious, but I have no Home Hub experience (yet).

1. Does Home Hub support WDS (Am fairly sure I read it does).
2. Planning on using WPA Personal (PSK) + AES. Linksys supports this, does Home Hub?
3. What's the default IP address of the Home Hub? (Am fairly sure they won't have changed it).
4. What's the default user name and password for the Home Hub?
5. Any gotchas I should look out for?

Thanks in adavance.

1. Yes.
2. Yes. It is preset to WEP so will need changing.
3. 192.168.1.254
4. admin admin
5. Nothing special about the HH. I've installed loads. Can do it in about ten minutes including a long discussion about how I like my coffee.

you can't do WDS and WPA at the same time, AFAIK.
