Is this wear on the rod and crank bearings normal?

you can probably change them with the crank in the car, but it will be awkward.

The big end bearing in the photo does need changing, but the mains in your photo should be okay. Usually the big ends go before the mains.

Thanks! If I start changing 'em, I'll change 'em all. 

I know it'll be awkward but, to my mind, it beats having to tear down the engine bay. Anyhow, I think I'll change all the bearings and maybe the crankshaft as well. So engine out it is, I suppose.
