David,

For reliable and long histories of fundamental data (including 
analysts' estimates) you really have to use professional data-
providers, and unfortunately (but understandably) that costs money. I 
use Datastream (who own IBES/First Call) and Bloomberg. Both 
Bloomberg and Reuters do not have as much historic data as Datastream.

Re Q2, I integrate macro, fundamental and technical data in quant 
models, and yes, due to the ThCSV-plugin (now to be replaced by the 
SQL-plugin)Amibroker allows one to combine this data, backtest it, 
etc.

This is my approach. In general, as others have pointed out also, 
find / create a niche, the precondition for success.

Just my opinion. Hope it helps.

PS
