I took apart my 2600 junior to fix a loose power switch problem. (contact issues) And hilariously, I stuffed some thin white cottony stuff inside the switch to add pressure, and while at it, I saw some really strange components in there, I found a large blue capacitor of a type that I dont know of. I also came across a strange silver tab thats next to the shielding, it has a little slit that looks as if you could put a Flathead screwdriver in. Can anyone explain those please? I will also like to see the pinouts for a component cable mod.
I cant hack yet... But I can help with "LazyMods"!!!

The Large blue capacitor is just a standard Axial electrolytic capacitor. I filters the input +9VDC to smooth out the ripples. Back then Wall adapters where efficient and dirty so the large capacitor would clean it up.
I am guessing the little metal thing with a screwdriver slot is right by this capacitor? If it is it is the tint control for the TIA chip.

I haven't poked around inside an Atari before but it definitely makes sense,

How to get composite video from your 2600 Jr.

Unfortunately it's the older mod, as the new mod's instructions are only for the big 4-switch 2600s. You'd have to reverse-engineer it to find other places to attach the mod to (I don't think Atari changed the schematics much over the 2600's run), but it's certainly possible.
If you don't want to do that, don't worry about it. The old mod works just fine, especially considering its relative simplicity compared to others. You just won't be able to use a PSone screen, or run it on some TVs. (I did it to a light 6-switch with a dead RF modulator, and it won't run on our 27" JVC TV. However, it runs through the VCR fine, and works on the other TVs and the DVD recorder just fine.) Its only other drawback is that you'll get some slight interference on the screen when some sounds play. It's there, but most of the time you have to go out of your way to notice it.
Here's the new mod:
