Developing as a team... Would like your input!

I have been playing league of legends on and off since 2009, I am now an avid follower of LCS and am currently playing on a casual 5's team who wants to start participating in smaller tournaments and potentially some type of league.

What I am looking for from you is some help on improving our team play as a whole, specifically I would like suggested resources or input on the follow topics from a strategic and development standpoint:

Pick / Ban Team Composition Level 1 Early Game Mid Game Late Game Warding / Jungle Control Rotation / Objective Control

I consider myself fairly well versed in the every changing landscape that is summoners rift. However, even with countless hours played and following high level play in the LCS/OGN/GPL and listening to other forms of discussion available I find I lack a detailed enough understanding to develop an easy to follow guide book that we can use to advance our team play on ALL of these topics. In fact in some cases as I try to piece everything together I get stumped by simple questions like an easy way to define the differences between early, mid and late game.

Any suggestions or information would be welcome. Detailed answers would be appreciated and don't feel that you have to answer on each topic if you feel strongly about one in particular.
