318 LA tear-down

I'm tearing down my 318 LA engine from a 1969 A108 van. Potentially going to rebuild the bottom and add new heads, cam and manifold. This van is for street driving and road trips.

Questions:
How much further into the block should I break it down? All the way and hone cylinders and install new pistons/rings and bearings?
I'm assuming yes.

What are the pros/cons of reusing versus replacing the crank and rods? (I could also add a stroker with tappet cam.)

Are these pictures showing normal build-up for an engine with 88,*** miles?

Thanks!
