Uneven pad wear can be caused by the fact that you corner harder under braking in one direction than the other.
I know for track days on a clockwise circuit my passangers brake pad ..gets more of a doing over than the drivers side one since its all right hand turns and I would have had a around 5mm difference between the two pads.
I don't know if 5mm difference is unusual for the road or not.
The garage should be able to tell you if your discs are warped or need replacing.
RE "the wire to the inside pad was broken", I suppose this is just the connection from the pad wear sensor?
What warning emssage do you get, "Warning:low pad wear - go to dealer".
I'm guessing you have worn your pad right through and are scoring the disc at this point..
Remeber to look all the way down the length of the pad to see the thinnest point to judge how much is left..
Hopefully you haven't damaged the disc too much, they are generally much dearer than pads.

Obviously i'm going to be getting new pads, but I'm worried about the condition of the discs, there is some slight scoring is this a problem?
Also reading through this forum warped discs crop up quite often, I have noticed some juddering under hard braking all though it is difficult to tell where its coming from. Any theories, and how do you know if your discs are warped.
I think my car also suffers from a problem with dry bushes as there is quite a lot of creaking under slow braking particularly when its been very dry or hot, could this be a factor.
One other thing, I noticed that the wire to the inside pad was broken, no brake warning lights come on except under hard acceleration, I think i'm about to answer my own question here, maybe the wire is making contact with a metal part of the brakes under acceleration thus making the circuit!
