If you are a Sonic.net customer you can set up a residential hotspot with
them:

They secure the line with IPSEC. It is what I use and I find it to work
very well.

I would vote "a. WPA pre-shared key". I would guess that both 'b' and 'c'
would require you to actually have a RADIUS server to perform the
authentication.

To get WPA to work on Linux you may have to do some extra work:
http://www.linux-sec.net/Wireless/AP/#WPA

Also I believe you'll have to make sure your hardware can do WPA:

'd' wouldn't be so bad either.  These days there are so many open APs that
if you turn on WEP and turn off 'broadcast' on your AP, then most people
won't waste their time with you
