Unit stats

I'm fairly certain that this has been asked before but I've trawled through the search for the past 30 minutes and discovered it will be quicker to ask the experts :
Is there anywhere we can get hold of a list of unit stats for each faction and what buildings are required to train each unit?
Clan Berserk had a very good list for MTW, so I guess it's just a matter of time before someone does one for RTW.

Also, whilst playing and hovering the pointer over some areas on the campaign map, I saw that the text for elephants indicated anyone could train them. They are a resource available to several factions but can they all train elephant units?
Is this the same for several units, or are units all faction specific? I saw Iberian infantry in a Numidian army and I know the Carthaginians can train them, so what's the deal? I can't fins any info anywhere.
