Answer 1

Idoc created by ALE is a means of migrating DATA between SAP systems. You configure logical destinations, establish some migrating criteria and the system takes care of getting your data from point A to point B
Where as Idoc created by EDI is described as the interchange of structured data according to agreed message standards between computer systems, by electronic means. Structured data equates to a simple and direct method of presenting the data content of a document. The method of ensuring the correct interpretation of the information by the computer system is defined by the EDI standard."
EDI is a technique used to communicate business transactions between computer systems of different companies and organizations. Note that sometimes the EDI mechanism deployed at a company is often used to interface to other systems within the same organization."

IDocs act as data containers in an ALE scenario. They are just a format of storing application data and then transferred using ALE. Take a look at http://www.sapgenie.com/ale/why_ale.htm and http://www.sapgenie.com/sapgenie/docs/ale_whitepaper.doc for further details on ALE.
