The oil will be in the stainless steel or silver colored part of the pump. If there is no access to this part then the oil is put in there by the manufacturer. I believe the small red plastic plug you speak of covers the overheat blow off valve. Just leave it. When you run the washer for a long time you may see some water spill out of there. The only way to change the oil is to separate the two pump sections. Not advisable without some knowledge and the correct tools

I assume you mean the rubber O rings inside the wand. I had to replace mine as well. I had to visit several plumbing supply stores to find one that fit. I ended up taking the end of the wand with me so I could make sure the O ring fit. The ring you are after is a number 5, but you need to make sure it is thick enough to make a good seal.

I may have left this up too long but.... what is the make and model of the pressure washer. if this is an AR pump there is not an inlet screen as part of the pump. It is part of the plumbing between the water supply and the pump inlet. Disconnect the hose connection pull out the hose washer and look for a plastic screen behind the hose washer. If you see nothing... disconnect all the plumbing that connects to the pump and test for flow while it is removed. If you have flow then there is something blocking the pump water supply inlet. If could be parts from the unloader valve. Pull out the unloader valve and inspect the hole. Make sure to lubricate the unloader valve with grease before re-installing the unloader valve.
I really need the pressure washer model number to point you to the parts your asking about.
