Seems the version you're using isn't compatible with Blender.
Your Blender is 2.69, here is a list of previous versions of Source Tools that should be compatible with your version.
I strongly advise on updating to the latest version of Blender, since it's very optimized and overall better.

the infamous "eyeball_r" error

...Which is what, exactly?

maybe he means the qc? I'm guessing it has to do wtih eye control like for example with SPLINKS models in SFM for fnaf, they have eyeball control.

Open up blender>go to file>import>Autodesk FBX(fbx.)

Load into what? SFM, Blender or what? Assuming you mean Blender, You COULD add all of the models into it and save it and use that as a "base" meaning if you need the models loaded in to do something with em you can always use the "base" save in Blender. If you mean SFM you could just export all the models at once as (i prefer) dmx format and do the qc's and the vmt's and vtf's and all those fun stuff.

You're in Object mode. Press Tab on your keyboard and then press A to select the whole mesh then u>unwrap

I usually go in the top right corner, there is about 3 white slashes there, I drag it out and create a new window with it and change it to UV editor and adjust the textures.

Ok thanks for your help

I have a question more
I have paint the texture in photoshop
But when i go back to blender it doesn't apply to the weapon texture. Does it effect when i submitted it at the workshop tool?

Create a new material and name it accordingly, then upload the textures to THAT material you just made then proceed to select everything and apply the mesh to that material and then unwrap it again.

2.75? Update to the latest version of Blender, then.

Fixed it. There was an empty model in the scene that kept making it crash.

When I export my model which is also rigged, textures, and scaled as well, I get a traceback error. I tried exporting to a different file path and no luck, I've never gotten this error before.
