I'm not sure of your other question, but I'm 99%-sure that LK still does not affect repair.
I can confirm this.My build is low on luck but does good repair, equal to a 6 LK build pre-wipe.It also doesn't seem to have any effect on the chance of breaking a toolkit.
What's the difference between:"It looks pretty broken""It looks a little broken"Which one can be repaired, which one is worthless (too many broken counts)?
