Engine swap (non mopar)

So first let me say I'm feeling a bit of shame, but I need to ask a question about a. . . . Toyota.:(. . . Lol

Anyway. I posted this on some toyota forums and those guys suck. They dont respond. I figured the question is general enough that I would ask you guys because you're awesome and always help me out.

I was gifted an 04 lexus es330. My sister's mom was in the middle of a trip back home when she blew the engine. It was 7000 to fix and the best she could ever get for that car is 5 so she figured "hey I'll just give it to Jon." The only problem is I've never replaced an engine before.

So question time. What are some of the routine things I need to do with a salvage engine before installing it? I understand the process of removing and installing, but for example I figured I should pick up a gasket set and replace all those before install. Anything as far as cleaning etc I should consider? I saw one article talking about disconnecting fuel the first time to get the oil pumping without starting the engine. All that kind of stuff.

Thanks for any help
