I need some help securing my wireless access point. I am new to wireless

I have no problems with my setup other than I need to secure this network
somehow.
I have a Linksys WRT54G wireless router that I would like to enable some
kind of encryption on it as it is running unrestricted.
It has the following options: WPA Personal, WPA Enterprise, WPA2 Personal,
WPA2 Enterprise, Radius and WEP.
I connect to it through from a desktop and a notebook both using a broadcom
chip set card.
iwlist gives me the following options:
wlan0 2 key sizes : 40, 104bits
4 keys available :
[1]: off
[2]: off
[3]: off
[4]: off
Current Transmit Key: [1]
Authentication capabilities :
WPA
WPA2
CIPHER TKIP
CIPHER CCMP
Which encryption method should I choose and how do I configure it?
The best option for a home network is probably WPA2-Personal (aka
WPA-PSK - pre-shared key). You configure encryption per WAP using
wpa_supplicant.
Put ...
key_mgmt=WPA-PSK
proto=WPA2
pairwise=CCMP
group=CCMP
psk=<your.pre-shared.key.here>
.... in the wpa_supplicant.conf file. The man page has examples to set
up the rest. You can generate 256 bits of random noise as your key and
enter them as hex digits for the psk if you're really paranoid.
