I think almost all of the questions are answered either in the documentation or the FAQ (http://code.google.com/apis/maps/faq.html) > 1.

It will find a route from A to B if A and B are within a certain distance of a navigable road and a route actually exists. The routing engine does use the Channel Tunnel between England and France and can use ferries. Directions are not available in all territories. > 4.Is there any limitation of the number of queries that a site can > request per a time unit? Yes. This is an FAQ: 15000/day. There is a maximum rate too which is faster than the average of 15000/day, but that rate limit isn't published and appears to vary depending on server load. > 5.

The API doesn't have all the built-in functionality of maps.google.com, although all (or almost all) the functionality can be built using the API. > 6.

Version 3 is a lightweight API designed principally for mobile devices. It is very different from v2 and has its own Group (see the Posting Guidelines for a link). It's very much in Beta.
