PS2 - need advice

[hallmark]

I'm a US player, and I'm speaking for a few people. Forgive the naive questions.

I've heard nothing but bad things about the next generation PES 2008, so I'm sticking with PES 2007 until PES 2009 comes out.
So, in thr meantime, my group will continue to play PES 2007 on PS2.

But we want to add more.
We want more teams, more players, and we want that info to be as updated as possible. We don't mind putting in the work to edit but we want to have a basis for the adjustments we're making. What do you suggest we do?

Is there any way to VIEW a comprehensive option file for PES 2008 without actually having the game??

Is there anything I can look at (online) that will have lists of updated teams with updated rosters and updated attributes?

Thanks in advance for your help.
