Answer 1

The command sent to SQL Server is

exec sp_executesql 
          N'SELECT P0 = @p0, P1 = @p1, P2 = @p2...',
          N'@p0 int,@p1 int,@p2 int...',
          @p0=0,@p1=1,@p2=2...

Note that 2 of the parameter slots in the call to sp_executesql are taken up with the NVARCHAR strings for query text and the parameter definitions thus "only" leaving 2,098 free for you to use.
