Well, if you wanted to do the best job with the honing then you would need to remove the pistons, but I have honed a few fairly fresh engines with the pistons still in and it worked out ok. That would also show if the bores are pretty round unless you use a bead type honing tool. Clean out the residue as best as you can after honing. That stuff shouldn't hurt the engine. Change the oil after running it a little bit, let it get warm. Have a machine shop take out some valves and see how the seats look. You might as well get a valve job done. Setting the valve lash is time consuming, but very necessary. You will need an extra set of shims to play with to get the clearances just right. New valve stem seals are a must and it would hurt to get a new set of valve springs. The springs aren't that strong but do weaken after time.
Good luck.
