Similar situation myself..had to replace the offside rear bearing, but ended up having to replace the rear trailing arm, hub and drive shaft. Picked one up from a salvage yard for good money though, so wasn't too bad.
As for the steering rack, I'm needing a new one too. I picked up a second hand one for about $150 and the mechanic is going to put it in for an hours labour, so shouldn't be too much. Have some new tie rods I picked up for $60 for both.
