Suspensions needs replaced, but confused

Stock 2013 Tacoma 4x4 DCOR V6 with 105,000 miles.

It is time to replace my struts/shocks and I figured now would be a good time to level my truck. From my research I have settled on B8 6112's front coilover/strut combo and

$455 B8 5100 Series Set of Front & Rear Shocks fits 2016-2023 Tacoma with 0-1" Rear Lift | Provides 0-1" Front Lift | Includes TrendsAuto Decal | 24-263108 24-186728

B8 5100 rear shock.

Questions:

• Is this a good combination? If not, are there any recommendations? I don't want to spend much more than these will set me back. If there is a more economical solution that still offers quality then I am open to that too.
• Which groove position should I set the front strut to achieve a leveled look?
• Does leveling require UCA's? I want close-to-stock alignment specs with perhaps +2-3 degrees caster for better highway tracking.
• Any driveline issues with just leveling the truck?
• Any reason to replace the rear leaf springs? They all seems in good shape. They were replaced under the TSB around 30k.

I don't tow with any regularity for it to be a concern.

I am open to any and all suggestions, so please let me know if I should go about this differently. I am complete newb on this and continue to confuse myself the more I read the stickies and misc. other posts.
