A simple web search can give you this information.  eg:

   www.cs.princeton.edu/courses/archive/fall05/cos217/reading/elf.pdf
or
   http://www.muppetlabs.com/~breadbox/software/ELF.txt

No. :-(  The best advice is to use the source code as your guide, ask 
questions on the mailing when you get stuck, and base you work on a port 
that is similar to the one that you are targeting.

The readelf program is pretty good at finding mistakes and problems in 
ELF format files.  Try "readelf -a <name of file>".
