I like to bring the head up to firm tension with just six hooks to make it easy to keep things level. Then, I go around the rim, adding in all the remaining hooks and nuts. When I encounter a misalignment of holes, a tweak with my awl helps straighten out the parts. The last step is to tighten all the hooks, taking a fraction of a turn at a time, raising the head to full tension. Well, it's a matter of taste - the tighter the head the brighter the tone, but the less bass response.
Some players prefer the head to be as tight as possible without breaking.
They determine that tension by experimentation. . . From here, it's a matter of reassembling the neck and resonator to the shell, and setting up the action. I'll remind you to take a look at the coordinating rod article for more on that subject.
