Mintex are not too bad discs...similar to OEM really.
The bearings tend to go on the Cups (well, most French cars in general), so its your call as to whether to replace all at same time, or just the disc, then the bearings...? Depends if you're paying to get them done, if so, then get the 2 done at same time if you've got a lot of mileage on the car!
