Yeah they should still be good at 60k. Obviously no two cars are the same, you could have one that's done 40k of town driving over potholes and speed bumps, and one that's done 90k on smooth dual carriageways and motorways, but in general the shocks will only really get tired towards 80k or so of varied driving.
New oem shocks aren't that expensive anyway as far as I know, and the VWR shocks I mentioned sound excellent, so there's plenty of scope for tightening things up in the future if you keep the car for a while.
Just get topmounts, bushes etc checked like you say, and you'll be fine.
I can't vouch for Eibachs, but the H&Rs give a nice balanced drop. I know from experience that fitting a spring kit is often a bit of a punt - you might end up with an odd looking rake or rear rake - but that's not the case with H&Rs. The car sits spot on.
