Setting up secure wireless.

[#1]

Hi all.
Can anyone give me some much needed guidance? Will be muchly appreciated.
My home router is a D-Link DSL-G624T and I'd like to set up a secure WiFi AP so I can use my Nokia N95-2 for downloading apps for that.
Which is the most secure setting to use WEP, WPA or 802.1x?
I've had a look at portforward.com and tried to set up a WEP connection but for some reason it won't accept the passphrase, even though it's 26 characters long.
Any ideas?
Thanks.

Thanks for the replies and links chaps
Although I seem to be struggling with one or two bits. I'm trying to go down the WPA2 route but I'm getting lost with some of the text input fields. I can see that something has to go in them but if I knew why and a few examples of what, things would be a bit easier.
(Bare with me as I'm a bit out of sorts with things, been a bit of a bad year).
