Others have noted very similar points, and I just hought I'd chime in with an opinion or two...
I prefer to do my door alignment without any of the door weatherstrip installed. It allows you to close the door without applying pressure to compress new weatherstripping. Likewise, I like to start without the door (jamb) strike installed. By doing these two things, you can focus on that which is of primary importance...the gaps.
Others coorectly state that you should adjust the rear door gap first. after this is done it makes adjusting the leading adge of the door to the cowl much more straightforward. After this is done, go back and put your strike on, and weatherstripping.
The front clip has extensive room for adjustment...if you make it through the doors, getting the core support, hood, and fenders located correctly will be a cinch...
