Valve Cover Gaskets

[KLC9100]

I have an 07 LS460. The Drivers Side Valve Cover Gasket blew out and is literally dumping oil. I have watched a few videos on replacing it and I'm confident I can do it. I'm having problems finding parts though. The video says to replace the gasket, seal, o-rings and washers for the High Pressure Fuel Pump. I can't find them. Anyone have any suggestions, tips, tricks, etc? I've worked on lots of Dodges and Jeeps. This will be by 1st dive into a Lexus. Any info would be most appreciated. Thanks...
