Should these bearings be replaced? '99 1.8 with 175000 km

Alright so I'll definitely replace the bearings. Would the piston rings be worn at this mileage? I can still see the factory cross-hatching on the cylinder walls. I'm just hesitant to change the rings, as then I'll have to worry about breaking them in while also tuning the motor when I put it in the car. Currently the car has a 1.6 and a megasquirt in it.

The rings are up to you. I am confused as to why you took the engine apart if nothing seemed wrong? Compression issues? If not then the rings would be fine but you took it apart so replacing the rings would be a nice thing to do. If I had taken the engine apart I'd replace the rings but if nothing was wrong with the engine I wouldn't have taken it apart.

If you've already got the crank out in the open you may as well replace the bearings.
As for rings, i'd personally replace them too, they're easy to do at this stage, but a dick to do once the engine it back in.
For break in, if the tune isn't good enough as is, just throw the factory ECU back in for bedding the rings etc.
