Noob- Help needed 86 K10 5.3 Swap

[XJDG72X]

Hey guys. First time swapper here. I have a really nice 86 K10 with 75K original mile on a turd of a small block 305. I recently picked up a 5.3 and 6l80E. I am going to keep the original instrument cluster.

Heres a list of questions I've got.

I want to run dual tanks, if I am not mistaken the stock tanks do not have baffles in them, should they be swapped out? Fuel pumps in the tanks, or inline?

How do I marry up the 6l80e to the NP208?

What temp sensor do I need to run the stock temp gauge?
What oil sensor do I need to run the stock oil gauge?

Truck is going to have a 4 in lift and 33's, currenty has 3.73's should I leave them or change up the gears?

Thanks for the help, I am sure I will have plenty more questions once I'm elbows deep
