Ok, I already have the PSOne screen so I guess I'll try using that to learn how it all works. So I would run the battery power directly to the screen's board and then run a line from there to power the NES board? Sorry if that's a dumb question, it's all a theoretical jumble in my head right now
Don't worry about asking questions that you think sound dumb - having as much knowledge as possible avoids mistakes, fried boards, etc. When you start working, take plenty of pictures so we can follow along. That way if you have additional questions (e.g. where on the screen board to tap the 5v from), we can point things out knowing we're all looking at the exact same thing.
Regarding screens, I think you'll be happy with the PSOne screen. For a long time it was every modder's bread and butter. As for ebay/Amazon backup monitors, every 5" and larger screen I've used have been problem free. 3" and 4" screens anymore are hit and miss, although more often a miss. Problem with the larger screens is that they're almost exclusively widescreen, which will stretch an NES' image unless adjusted in the screen's options. When you change a 5" screen to 4:3 mode, the viewing area is maybe a little more than a 3" screen. I have no problem with doing that in my projects, but I know some people don't like using a screen with black bars on the sides.

Ok awesome, all great info. So I guess I just need to make sure I have everything I need before I start... I already have the NES2, a controller, the PSOne screen, a soldering iron and solder, wire and resistors.
What else do I need? Those 2 batteries, a smart charger, a protection circuit and 3 white LEDs for the screen? What do I need for a power jack, headphone jack and potentiometers?
Oh and I also need those parts for the component mod, too.
For your power jack anything that you have both the male and female ends works fine. In chevy's pic you can see that she's using the power jack from a PSOne screen (female) and a PSOne power supply (male) to power the screen and NES.
(This looks like a facebook link, so the image will be broken when fb changes their links.)
If you don't want to hack the barrel connector off the end of your PSOne power supply, find some other male/female pairing that you can wire to your charger.
What else do you need? A case to house it all in, naturally. But if you don't know size/design at this point then you can just work on the electronics so you know you have it up and running. The PSOne screen has digital volume control, so you won't need a potentiometer for that if you don't want it. Headphone jacks are best salvaged from old dead electronics, but you should be able to find them at Radio Shack, if you can find a Radio Shack. Recommend buying online instead; it'll be cheaper. I can't think of anything else that you'd need at the moment.
A protection circuit is a circuit designed specifically for your batteries that protect them from being overcharged or over-discharged. In a nutshell, if you hope to charge a battery by applying a steady voltage directly to the battery, it can explode/start a fire/both. Anything that needs to be connected to the batteries must first go through the protection circuit. If your batteries are a night club, think of the protection circuit as the bouncer.
no. they are 5mm, too big. you want 3mm leds. you can get packs of them on ebay for quite cheap. you may also want to go with more then just 3 leds. that's the main problem with the psone screen. removing the original lighting does greatly increase battery life, but you can never quite get the brightness as good. i use 6 leds in a psone led mod, and i'm still unhappy with it's brightness. but, i'm kinda picky about screen brightness. lol
