If you have 2 music expressions in a score, e.g.
\new StaffGroup << ... >>
and
\new GrandStaff << ... >>

you must combine them into one music expression.

You probably want to do that like this:
<<
\new StaffGroup << ... >>
\new GrandStaff << ... >>
>>

Regarding the other problems: Can you try to isolate your problems, i.e. 
create a fairly minimal score that gets the same problems? This is often a 
good way to understand what went wrong, and if it's a bug, it will be a lot 
easier for you to explain the problem.
