clean bolt holes and check for wear; be ready to rethread them if they are damaged (you don't want something to break in there )

As far as rebuilding the engine goes, control everything. Use plastigauge to find the correct clearances for conrod and crank bearings. Get nissan ones (they actually offer way more sizes than every other maker). Unsure of something ? Do it again. And use assembly lube, tons of it.

Also, consider bearings as fuses. They are the weak link that gets destroyed so that expensive other parts don't (if you are fast enough). although they do wear out with mileage and bad oiling conditions, and if i remember correctly yours has a high mileage. Don't forget to add "oil pump" to your wanted parts list, and have that block cleaned in every oil gallery.

High mileage usually means oval cylinders, meaning you need the cylinders checked for roundness. It probably needs a new bore, meaning new pistons too. Do NOT get the block machined without the new pistons, they need to be adjusted (measurements are one thing, but having both pistons and cylinders measured by the same company is better)

As far as the head goes, have it checked for flatness and corrected if it is not (same goes for engine block). Considering $$$/power ratio, i can't see the point in porting it or changing cam(s), really. That money will be better spent in new pistons and conrods, even if it does not up power.
