I've only ever used Crowbar not Blender.

Download this tool

Once you have the model decompiled you will have to export it to blender to rig the bones.

This video might help but I've never used Blender before.

Someone with experience with modelling would be able to explain it properly but it's not that difficult to port from l4d2 to CSS.

Ok so... i got everything, or at least almost everything, and i got to this point:

Here i can delete unnecessary bones and follow the video, is very straight forward easy to follow (ty for sending the video  ), and because my lack of expirience i dont know how to; 1st: download an add-on called Copy Attributes Menu (all i found was a script),
and 2nd: how do i remove/change this skelleton part? (its suppoused to be only 1 stick with 2 balls at each end)

Sorry for my lack of knowledge but is all i did today lol

Thanks for helping

Update:

So after some help i finally managed to finish connecting all the bones and tried to parent the bones with the mesh BUT i get an error saying 
Bone Heat Weighting: Failed to find solution for one or more bones
This is how is looking so far (With the extra bones):

(No extra bones):
