I would like some assistance on building this circuit before I purchase the components from Mouser Electronics.
Just wanna make sure it works, according to the circuit I found online.

I understand how to hook it up.
I don't understand why I need the resistors and capacitors, or why those specific values are used on the IC with the crystal.

The main question I need answered ASAP is... Will it work with the components?

Some references and reading material listed below.

4. JK Flip Flop and T Flip-Flop (Video)
5. My Cart on Mouser, so far

I don't see many other people that wanted to do this on All About Circuits, but I did see this post Lazy 4521 Chip - Odd Problem

The data sheet is so old it seems, it's just a lil difficult looking at it. I'll try to give it another read.
