Putting together my first custom stick, need some help

So on the neutrik adapter, what cable would I use to go to the PS3? A normal USB cable?

Any of the longer A to B cables, like this one:
StarTech USB Cable, Male A/B, 15’ Black

Amazon.com: Black Hi-Speed USB A to B Cable male / Male - 10 ft: Eforcity

This is the same thing, right?

pretty much

Ok, so on to my next question, are these the same thing? Lizardlick is out of LL Quick Connect, .110" Insulated (Which are what will connect to the sanwa buttons if I understand correctly, just like my SE stick) so will these do? Amazon.com: .110" 22-18 Guage Vinyl Female Quick Disconnect 100pcs - Red: Home Improvement

Also, where can I find those awesome sleeves to keep the wires organized I’ve seen in peoples sticks?

Again, thank you for any answer, hopefully once I’m done I’ll know enough to make my next stick without having to bother anyone.

Yes, same as Lizard Lick.
Although not exactly as your Mad Catz, unless you changed everything.
Since Mad Catz is Open Barrel, and very few people on SRK even use them.

I am one of the people.
Such small number, that you can count without extra digits on your hand.
