LUC100290LP are the front [cambelt end] seals they should be black. LUC100220L are the rear [distributor end] seals and should be red. It's common now for them all to be black so go by the part numbers: LUC100290LP cam belt end, LUC100220L distributor end. These can be changed without having to remove the cam carrier assembly and cams.
As you will have to remove the cam belt and pulleys you will need that locking 'tool' to get the new cam belt fitted. It's a good idea to replace the coolant pump and thermostat at the same time too. Removing the spark plugs will make turning the engine over by hand easier. You do that to align those time marks up. Last bit of advice: take care to refit the cam pulleys correctly. Without the pulleys fitted the cam pulley locating 'roll' pins should be at: 4 o'clock for the inlet cam and 7 o'clock for the exhaust cam. When you get the cam pulleys on, the cam pulley's the "Exhaust" marks point at the windscreen. "Inlet" marks point at the radiator.
