What is everything needed for my SYE upgrade?

So I'm planning on doing the SYE and rear CV DS upgrade, and would like to upgrade a few other things, but am just trying to figure out EVERYTHING i will need to do this. I'm a tad bit unsure of everything that I will need for this upgrade and could use some advice. Any help is appreciated!

SYE kit: This one seems easy. Probably going to go with the JB Conversions or Tom Woods package. Also heard that it's better to get the SYE kit first, install it, take all the measurements, THEN purchase your DS.

Rear CV DS: JB Conversions or Tom Woods. Also heard Adam's Driveshaft has good products and a good deal as well.

NP231 Rebuild Kit: I'd like to do some preventative maintenance while I have it open, but there are tons of rebuild kits, with lots of varying prices. JB Conversions looks like it has a good one, albeit the most expensive. There are some on Amazon that aren't too expensive that look like they include everything, along with a new chain that runs around ~$80. Now I know that you get what you pay for, but some advice here is needed.

Rear Adjustable Upper CAs: Looking at the RE Super-Flex control arms (http://www.quadratec.com/products/16312_104_07.htm).

-Now the rest of the stuff I'm unsure of...-

Rear Shock Mount Relocation Brackets: Do i need these? It looks like my shocks will hit or be close to hitting the coil mount on the bottom once i change the pinion angle. I've seen people cut off part of the coil mount instead of relocation bracket on the shocks. (http://www.quadratec.com/products/16054_000.htm)

Rear Coil Spring Relocation Brackets: Same as above... do i need these? Lol. The springs will be crooked with the pinion angle changed as well. Nth Degree makes some brackets that look to be decent (http://www.quadratec.com/products/16500_450.htm)

Rear Track Bar Relocation Bracket: Jeep already has one that came with the 4" RC lift P.O. installed. But it looks like there is a CV bracket I will need to install with the new driveshaft? (http://www.quadratec.com/products/16311_623.htm)

Rear Track Bar (Adjustable): I have my stock track bar, but will I need an adjustable one now? I mean it couldn't hurt so I'll probably just pull the trigger on this one as well. Looking at RE RE1620 Rear Adjustable Track Bar (http://www.quadratec.com/products/16311_603_07.htm)

Tools: I've got a good set of snap-ring pliers and all the necessary tools I should need, but I think someone said I would need lock-ring pliers too? And a huge socket for the SYE install portion?

I'm going to be putting on new shocks as well (Rancho RS9000XL) and possibly new springs but not sure on that yet.

Is that everything? Too much? Too little? Thanks everyone.

There is a thread called "What is an SYE and why do I want one". It has pretty good details.

Get upper and lower control arms and get something with either true Johnny Joints or MC duroflex joints.

231 rebuild kit is overkill unless you've really had a problem. If you want to do it, knock yourself out, but not necessary. Personally, I'd use that money to upgrade to the JB Conversions Super Short kit. It's more expensive and requires going to electronic speedo correction, but it is a better setup in many ways once installed.

Don't use the shock brackets. Grind down the back of the spring perches instead.

Springs being bowed is not really an issue. And most of those brackets will add lift in the rear if you use them.

Angled CV track bar bracket is necessary due to extra rotation of pinion.

This shouldn't change your need for an adjustable track bar. Either you need it now or don't.

IMO you want lock ring pliers, nice big ones, not snap ring.

Here you go: http://www.sears.com/craftsman-exter...1&blockType=G1

Just about every Sears has these in stock for $15. They worked great for my SYE install.
