I need a little help picking out whats best.

Okay so im saving up for a lift kit for my truck. and i wanted to get new uca's and extended brake lines also but i want to buy it all and put all on at once so i dont half to go back and take it apart multiple times. I have done alot of research on this but im still confused and just need a few answers thanks.

So for a life i was thinking an OME 3" lift with AAL and 886 coils.
-First question is, i have an 06 DCSB and it only has the 3 leafs on it/ the 2 with the overload whatever its called. Should i get the TSB done first or wait
-Next question, how does the bilstein 5100 work with the lift or is it better and more worth it to do the OME shocks .


For UCA's i was gonna do total chaos.

Last the extended brake line.
-My question is where should i get those? i was maybe looking at the ones wheelers has on there website.

Thanks everyone
