there is no need to put new rods in, unless the factory units have been stretched too far. if they are within spec, then just have them bead blasted and polished. that will add much strength to the rod and allow you to run a healthy amount of boost. you dont need special pistons, oem replacements will work just fine. itm makes quality aftermarket pieces and they come with wrist pin/rings out the box. if you really feel the need of strengthening the block you can either install a block guard before you do final machining on the block or post it. both are cheap methods and both will provide ample support for daily driving use.
if you have some time with a butterfly grinder, and have the balls, id suggest doin mild work on the head. simply clean the ports out, flatten the floor, and match them to the IM and EM. some factory build tips for the valve train would be to have the springs heated to make them stiffer, have the valves re-cut, and have a 5 angle cut put into your valve seats. a basic r&r of the head would also be a smart idea.
hell, id just buy another d series engine and slowly rebuild it over time. by goin that way you would save yourself downtime. plus, used d series arent expensive. you can easily pick up a vtec d series for no more than $300 including axles.
most important tho is to have good machine work done and have the bottom rotating assembly re-balanced to 7500-8000rpm's. this will save wear n tear on the rods and bearings, giving you more life out of your engine.
