Bicycle Mechanics - Which brake pads to use?

I have a Salsa Casseroll (http://salsacycles.com/bikes/casseroll/) and I was looking to replace the brake pads. Now, I'm not really mechanically inclined so I was kind of flying blind when I bought some brake pads off of the internet. The bike has Tektro Oryx Cantilevers so I bought some brake pads for cantis. I got them in the mail yesterday and tried to put them on today and they are clearly not the right ones. I was looking specifically for Kool-Stop salmon brake pads, so if someone can point me in the direction of the correct brake pads for my brakes I'd be very grateful.

I'm a year round commuter and I have canti's on my worst weather bike. I've used Kool Stop Thinline the whole time. I *think* the Salmon are the rain pads and all the other colors are basically the same, but I've only used the blue and the black. Make sure you toe them in a bit, I use a couple rubber bands around the tail of each pad as I'm setting them up to achieve this. Here's an amazon link to the pads:

use v brake type pads that have a threaded post

Sorry, it looks like your Oryx canti's use threaded pads, like the ones on V-brakes. Here are some better choices:

These are the same ones, right? http://www.amazon.com/Kool-Stop-Mountain-Bicycle-Threaded/dp/B001CJZ0Q2/ref=sr_1_2?ie=UTF8&qid=1315678851&sr=8-2

I'd rather get them from Amazon, 'cause I've got amazon prime :x
