You should be able to create the alpha layers by following a few of the tutorials here: http://wiki.secondlife.com/wiki/Clothing_Tutorials (since alpha layers are system layers and not specifically mesh related)

The two first links on the page is for system/avatar templates in ps format.

Then you should check a couple of tutorials on texture painting in Blender, which will show you how to texture paint in the avatar mesh to get the result you want. A few of these perhaps: http://search.yahoo.com/search?ei=utf-8&fr=aaplw&p=Blender+texture+painting+tutorial

ok so i get you need to do on the templates but I dont get how you can make it exact to the mesh item you made - i can unwrap the mesh item and export that into photoshop but there is just no tutorials on how to make it an alpha - i know im missing something really easy here but I  can't see how using the clothing template can get me to make an exact alpha for a mesh item i have made? any more hints al all please would be gratefully recieved thanks!

Hi jamie. Perhaps my last reply should have been longer and more detailed. :smileyhappy:

There are more than one way to create an alpha layer that fits with the model you made. Below is mine, which may not  be the most efficient way. I use Blender to create the layers, and sometimes use a Photoshop type program to clean up the textures before importing. The photoshop clothing templates I linked to above is strictly only necessary if you need to do some work in photoshop. Also, creating alpha layers are exactly the same as creating other system clothing layers. The difference is you use transparency in stead of colors when making them, and apply the textures to alpha system layers in world.

What I do is this.

First, I split the screen with a 3d view in one part and the uv/image editor in another one.
After I add and assign a new image (make sure it has alpha enabled) to the uv map for the avatar body part I want to make the texture for, I enter texture paint mode. (You do the same for each body part you want an alpha for.) You find texture paint in the drop-down menu blow the 3d view where you go to select object-, edit- and weight paint mode.
I also make sure 'image painting' is enabled in the image menu below the UV/image menu so I can paint directly on to the image in the uv editor.
The, in the tool-panel in the 3d view (t-key to toggle) you should fine the brushes you need. I usually use the 'F Brush' from the brush selection. 
Below the brush selection, there is a 'Blend' drop-down. This is where you choose to paint with alpha or not. Use 'Add alpha' or 'Erase alpha' depending on what you want. This brush setting also works in the UV/Image editor.
I then paint directly onto the avatar, with my model on top so I can see where to paint. Normally, I paint the 'outline' - the borders between alpha and no-alpha, this way, (hope you understand what I mean), and then I fill in the rest in the uv editor. I also make sure I overlap the edges for the different parts in the uv map to prevent artifacts after imprting.
Save images as RGBA, import and apply on an alpha layer, and you're good to go :smileyhappy:

Hope this gives you a bit more to go on. If there are any specific functions you don't know where to find in 2.6x, just come back and ask. :smileyhappy: Perhaps someone else comes by and gives a better explanation and procedure.

It was not a very comprehensive or well written example, but hopefully you get what you need out of it. :smileyhappy:

Be sure to post back how you get on with it?

Great news, jamie! Glad I could help :smileyhappy: Before you know it, you've found your own and better way to make whatever mesh or texture you want.

You're right about practicing - there's no substitution for it. That's the only way to get better at making stuff.

Good luck with your Blendering! :smileyvery-happy:
