Building on above, we similarly do
1) Deploy Image task
2) reboot task
3) deploy application 1 task
4) deploy application 2 task
5) etc...
However, we also build in a Gather HW/SW inventory task. We didn't use to but then realized some machines that were imaged and not used didn't have any inventory info.
Also, the last task for us is always a system configuration task that adds machine to the domain (and puts it in the right OU). This is a visual cue for the technicians that the image job completed successfully when machine is at the CTRL ALT DEL screen.
Good luck.
