Those 90s rigid MTBs make great commuters. Good to see another one getting revived.
Chances are new pads would suffice for the brakes.
Clean & lube pivot points, cables etc. and they may work fine.
Shouldn't be any need to replace DER's. If you are having a problem with them, it's probably the cables & hardened lube.
