suspension upgrade (koni yellows + H&R springs) - anything else to replace?

Hi, I just purchased a new Koni Sport Performance Suspension Kit [KON1140-1871] for my 2009 e90. This kit consists of koni yellow shocks with H&R lowering springs.

According to my reading on this forum its recommended to use Z4 rear and E36 M3 bump stops for the front when using lowering springs for the E90? Can anyone confirm this and also confirm part numbers please?

Is there anything else I should think about replacing whilst doing the suspension upgrade? as I'm planning to give the car to the mechanic in a week or 2 so just want to do my homework and get everything needed for a one time install.

Many thanks in advance,
Omar
