Physics are physics, whether we’re dealing with wood, aluminum, or carbon arrows. After deciding on what spine aluminum arrow to use, we start playing with tip weight and length to get the flight characteristics we want, just as we wouid with wood.
Some would disagree, but generally people who want to shoot targets want lightweight arrows, for flat trajectory, while people who want to hunt want heavyweight arrows, for penetration.
Since you state you want to shoot targets, your choice of 30-35# bamboo shafts for your 30# bow seems reasonable. With 40-45# shafts, you would have to select a heavier point to get the same flight characteristics, which would give you a more curved trajectory and thus limit you to shorter ranges. Just experiment with different points until you find one that flies best for you.
For regular wood shafts, like cedar, most people prefer glue on points, which come in different sizes, from 5/16-23/64, depending on the diameter of your shaft, and different weights, from 75 grains to 145 grains or more. I would suggest that you start with 100 grain points. Most people taper their shafts to fit the point, using any of a number of taper tools that are available, from cheap to expensive. The taper tools usually have one end that has a long taper for the point, and the other end that has a short taper for the nock. Probably the most common glue for mounting the point is Ferrel-tite, which is heated over a propane torch and dripped or smeared onto the taper. Most people use the same glue for the nock they use for gluing on the fletches, like Duco.
This might not be the same for bamboo; somebody who regularly uses it should probably chime in.
