Rear lower control arms or upper control arms first?

I know I saw a thread where someone asked this before but I can't seem to find it. Hoping for some sort of Black Friday/Cyber Monday sale from Savvy and was going to get either rear upper or lower control arms. I don't think there is a whole lot of adjustment that I can do with just uppers or lowers but is there a better option to start with? I have a 3" Zone lift with 35s, starting with the rear axle to build towards a tummy tuck.
 
If you can only go with two at first I'd go with the uppers. That way when you raise the pinion angle you do so by extending their lengths which slightly moves the axle back a bit. That helps since installing a suspension lift slightly shortens the wheelbase.

If you have an sye, then go with the uppers. You will need the uppers when the sye is installed. My LJ without an sye actually needed adjustable lowers to get the correct pinion angle. The uppers are adjusted as short as they will go, but it wasn't enough. Had to extend the lowers to get the correct angle.
 
Nothing came up for Black Friday on the Savvy site, regardless of a Cyber Monday deal or not I'll be ordering rear UCAs tomorrow.

I don't have an SYE yet but I know I'll need one to bring the belly up in the future. At what point will I need an adjustable track bar? I just have a stock rear track bar right now and I'm not sure if a relocation bracket came with my Zone 3" kit. If I start adjusting the axle with control arms will I need an adjustable track bar back there?
 
Gotcha, I didn't install the lift myself and it's been on for a few years.

So will I need an adjustable track bar to accomadate the changing angle of my axle? I know that isn't the purpose of a track bar but with the adjustable end being able to pivot that would make things line up easier right?

I just used and angled relocation bracket when I had adjustable control arms and a SYE.
