How would you rebuild this 318?

I have a knock in my 318. Its definitely a lower end knock. My guess is a connecting rod. This is what I have;
Bored .020 over
stock pistons, rods, crank
Compression ranged from 138 - 143 when I last checked it
Comp cam XE262 262/270 duration, 462/470 lift
302 casting heads milled to 58 cc with 1.88 intake
Edelbrock Performer intake
Edelbrock carburator 1406 (600)
Headers
833 4 speed
3:23 sure grip
275/40R17 tires

This is in a street car with no intensions of racing but, like most people, I enjoy the feel of a car taking off when you hit the gas. I would describe myself as "good" with engine understanding but far from excellent. My questions;

Would I bore it to .030 and change the pistons?
Is the cam good or should I reconsider?
Should I change the heads to a 2.02 intake?
Does the knock mean I need a new crank and rods if I'm right on my assessment?
If yes to a new crank, do I consider a stroker kit and would my existing top end work with a stroker? Or is that just a whole new bag of bolts.

Thanks for your input.
