Advice needed: Taking care of a gaming laptop for dummies and other questions

Hi, I’m buying my first gaming laptop after only using mac laptops my whole life. The one I decided to get was the Lenovo legion pro 5 with RTX 5060, 32GB DDR5, and 1TB SSD. As a mac user all of this is very unfamiliar to me, I don’t do anything like clean the inside of my mac laptop ever or install any programs really. I only want to use the laptop for gaming so I’m wondering a few things. First, will it run games like the Last of Us at high quality and smooth framerate? It doesn’t need to be anything crazy but I do like those kinds of games so I’m wondering if the laptop can handle that (I’m assuming it can from my research), second I wanted to ask was how do I take care of it? Are there any specific programs I should install when I get the laptop to optimise performance and make sure it lasts a long time? How should I clean it? Can I use it on my bed on my lap if I put it on a cooling pad? Around what should be the temperature? And what is thermal paste? Thanks so much. I don’t really know any of the specific components or anything like that so I’m really confused when people start talking about the fans and the CPU and stuff so maybe an explanation of that stuff would be helpful too.
