The bubble hash process is designed to capture that goodness.
The rest of the bud is still useful. Time-wise it might be better to use a solvent.
Phatty is right. Bubble hash is a physical separation, not a chemical one. The idea is that you are knocking the bulbous trichromes off the plant, and then sift them out. By running your material in a grinder or food processor, you're already busting up those heads. This spreads the oils they contain onto the plant matter. You wouldn't notice any real difference in the quality if you smoke or solvent extract the plant matter at this point, but it will severely diminish your yields for bubble hash.
Busting your buds up also has a secondary effect of making it easier for chlorophyll to be extracted from the ruptured plant cells. This will result in a "greener" tasting product. You can probably rinse the wet hash with lots of plain water to remove this, but why add an extra step?
