PB Blaster works WAY better than WD-40. Just saying. I spray metallic parts that I don't want to rust while sitting with WD-40.
To answer the OP: Just take it slowly. After you get the gas lines, I suggest using zip-ties to hold the lines up (I tied them to the brake lines). I also recommend putting a bag over the end so that debris doesn't get into the fuel feed.
You'll need to drain the oil from the engine (duh), and from the power steering. Draining it from the transmission is optional (might as well and change the fluid while you're at it, right?)
I recommend using an engine hoist, and extending the boom (arm) out as far as it will safely go to give you more allowed height to raise the engine.
Using a leveler will help a LOT, especially for reinstall.
Be aware of the upper radiator support and be careful not to damage it. It is very easily bent.
Most important thing: take your time!
