I would appreciate it if someone could explain upon it a little more, or possibly do a quick vid tut

Hey man i have been attempting your tutorial several times, but seriously its a bit messy and dated. Me and many others would love if you just gave it a quick update to clear some stuff out.
For instance i had no idea what whas going into the Param2d in the ramp part. and the part where you connect everything up is really hard to follow.
what goes in the param2d in the ramp part should be more than obvious :O
the ramp, the texture you use to change the shading, i added a sample picture above the arrow
What exactly don't you understand there?
It's a 1d Ramp - basicly a strip 1px height and Npx length (i took 256px) on the left is your darkest value on the right is your brightest value- so if you'd put in some harder steps you'll get harder steps in your shading as well.
What TF2 did is create a ramp thats not linear from black to white, it has more lightvalues but never reaches full brightness, as the half lambert brightens things up anyways and it gets more saturated/reddish in between the mids and the shadows.
also read the terms i've written on the top of each image, if it says ramp * half lambert it means you have to create a multiply node and multiply the result of the ramp part with the result of the half lambert part.
So http://polyphobia.de/public/tutorials/TF2shading/012.jpg means that you take your albedo, create a multiplynode, plug the albedo in slot a and the result of ambient+ramp*halflambert into slot b
its just simple math +,-,*,/ really just read it and not only try to look at what the images say
If its the math thats too hard to understand try http://www.khanacademy.org/ he is awesome and can teach math way better than any teacher i ever had, he can show you why you do things as opposed to brainbless repeat what the teacher tells you.
the most complicated part in the term is the dot product part i guess, maybe this will help ypu to understand it http://www.khanacademy.org/video/vector-dot-product-and-vector-length if you think of it as the term on a per pixel level its somewhat understandable i think - if not you can always start earlier in his math tutorials
knowing the math will definitely help you in the creation of shaders, because it is all math and in a lot of cases very simple math such as + and * and no i don't understand every node out there, in some cases i just know the result and use it, but thats experimentation, i can't take that away with a more complex tutorial, because the one moment where it goes click in your brain will be taken away and exchanged by "do this and that to get this and that" - if you want to go the even better road take the valve term http://www.valvesoftware.com/publications/2007/NPAR07_IllustrativeRenderingInTeamFortress2.pdf and try to understand it backwards engineer it as i did, maybe make the same mistakes or see where i did the mistakes, it will definitely take some time but imho its worth more than just copying a tutorial
About the tutorial itself, i took some pictures while i was in the process of trying to understand valves term, i definitely made mistakes, especially in the specular and rimlight part. Moddb took them and made that tutorial out of it (i don't even think i can edit this page, as its not been created by me initially)- if you want to understand what i'm doing just read whats in the upper left part of each image, thats the name of the term, the image on the left shows the nodes that are needed to build the term, and the image on the right shows the result of the term applied to the heavy.
I will see if i can add some text to make some parts more clear - but don't count on it too much
makes understanding vector math really easy
i agree with neox - it's all really simple math and once you got your head around it it's quite a bit of fun as well.
Which reminds me, I need to look at that valve paper again...so I can around making this shader in HLSL.
What i was looking for in my first question was just a video on how you setup the material
it is junior high level math, not the nodes themselves for sure, but the connections in that shader are all just addition and multiplication - if you just want to copy what is there, why do you need a video?
http://polyphobia.de/public/tutorials/TF2shading/shader.jpg
just create all the nodes you see there and wire them as shown there
the problem is, you will never understand whats going on (and why some parts of this super old and very first shader of mine are wrong), and if you made a tiny mistake the results can be very different and you will never know why.
How easy should shader creation be? i mean i'm an artist myself, not very technical oriented (but interested), i'm pretty bad at math, at least i thought so until a friend of mine showed me khans academy and i learned to see some things i never understood because of brainless repetition. And even i can understand what most of the stuff in the nodes are doing, i cannot read code at all, its like a foreign european language to me, i understand stuff every now and then but it doesn't make sense to me. But nodes or visual shader creation is understandable to me because its visual and covers a lot of the logic inside nodes, you don't have to understand the insides of the nodes - even though it will help you a LOT but you at least have to understand how and why to connect them and this is in most cases - as said - math for braindeads
if you don't want to work with that, grab yourself some master shader and live with it, use Material Instances to exchange textures per assets and tweak stuff - but then you are limited to what the master shader offers you
