Implementing iProc/PO

[Dinesh]

Hello Gurus,
Could anyone give me insight from where to start if I want to implement iProc/Po modules. I am looking for general guidelines e.g what accounts I should need to setup ,what workflows to look for ,what is the significance of inventory into it, what customization is mandatory and what are essential setup steps.

All in all I am looking if someone can give me good kick-start.

Disclaimer : I have worked on PO/iProc/GL/AP from end user point of view/technical developer but don't have much insign whats goes on behind the seen.
