First line single staff, then double and some other beginner questions

[Hendrik Maryns]

Hi,

After some experimenting a year ago, I started again now with Lilypond 
2.6.0 becoming available on Windows (with an easy interface, 
congratulations!).

In trying to make my first piece, I'd like a first staff for the 
preamble (voorspel, what's it called?), then from the second line have 
two staves.  I have this now with the following code, but the splitting 
up in two << >> contexts seems inappropiate. Also, now the \time 
signature is ignored in the second and further staves.  So how can I 
achieve this?  By hiding the second stave on the first line, or adding a 
new stave only at a certain point or...

Some more questions: how to add Unicode in the title (I want ë. 
TeX-syntax \"e didn't work.)
And I'd like a pianostaff-like brace in front of my staves, but adding 
\pianoStaff messes up the text and all.

Also, can I suspend a {}-group and continue it later, or do I have to do 
the first voice in total, then the second.  This is a copy of existing 
music, as you might have guessed, so that would be easier to type.

A bunch of questions, I thank you for your patience!

TIA, groet, Hendrik
