You NEED to have the block measured to verify the bore and roundness of each cylinder. As long as it is within spec, you should be fine with a light hone. I would strongly suggest new OEM rings, or a quality aftermarket brand.
Aside from that, I would say that you can get away with replacing only the seals you have to remove. The oil pan seal, the o-ring on the center main cap and the oil pickup tube gasket are the only ones that I can think of that have to be removed to take out the pistons and rods. Obviously, the front and rear main, rear main housing and water pump seals should be replaced, but you can get away without removing the balance shaft gear set and the oil pump itself.
Since you're removing the rods, I would verify that the surfaces of the journals are good, then buy the same color rod bearings from Honda. Depending on the rings you buy, you're looking at $175-250 in bearings, rings, gaskets and seal to complete the bottom end. Of course that doesn't count a head gasket, timing belt, injector seals, intake and exhaust manifold gaskets and any machine work. But, the finished product will be fairly rewarding.
If everything sounds more expensive than you planned, it's because you're changin pistons. Otherwise, you could find a low-mileage engine, swap the head, check for shavings and only worry about top end stuff. Either way, this will be more fun and will make better use of a higher-rpm camshaft.
