Got the intake off the car to do a Fast 92 swap. What else should I do for preventative maintenance while I'm this far into the motor? Oil pressure sender?
Get a paint brush and good vacuum cleaner and make sure you get all the loose sand and stuff before pulling it. This should help prevent any going into the intake ports. You won't believe how much is laying around.
There was a TSB on the knock sensors where a dam of RTV is used to prevent them from getting wet. Might want to search and see if it applies. Check the vacuum lines behind the intake. If still running the original AIR setup, might want to either clean or replace the passenger side valve which sits behind the driver's side head but requires intake removal for access.

This is from the TSB for a 2002. Steps 1-5 were replacing the sensor which you aren't doing. For some reason they don't run the RTV all the way around the seal for the sensor and they don't do the front sensor. There is no TSB for the 2003 or 2004 and the repair procedures don't mention using RTV so I assume they must have improved the the seal to keep water out.
How would I ever know I had steam problems? Is this boiling coolant at the high point of the system?
there are coolant lines running under the intake, some intakes don't allow enough room under them so you need to relocate them. Some just flatten them out for clearance, but I feel using the kit I mentioned allows the air not to be trapped in the heads.

Also, I noticed when I pulled these injectors out of the fuel rail, there is an additional o-ring in the fuel rail in between the injector and rail. Is this normal?
No no, the injector has 2 o-rings on itself. There's also an o-ring up inside the fuel rail that the injector top rests against. I thought that was weird.
