This part is fine.

I tried the next part. It didn't work nicely for me. 

So what I do now is:

Firefox + FoxyProxy

and now I can set my proxy individually per site. All the internal work
stuff accessed from home goes through the proxy, except the three sites
only viewable from the outside; and everything else bypasses the proxy.

Much better than trying to deal with a global proxy (although foxyproxy
will do that too if that is what you need.

And dispense with all the tsocks stuff.

I see recent KDE now also supports socks. This is a nice new addition
so konqueror can also use it.
