Depends how you want it to look -- I often use two staves for drone+melody
on cello (since Britten sometimes uses that in his cello suites*.  And
because I wanted to show off some of Lilypond's neat featuers :)

* ok, he doesn't use it just for a simple drone.

In your case, threads are the way to go.

Absolutely.

I can't think of any reason why not, but I haven't personally done this so I
won't
guarentee that it'll work.

Try it -- insert this snippet into a file:
<
{a4 () b c d\fermata}
\context Thread=other {a8 () g fis4-. e4.-- d8}

(I haven't tested it, nor am I positive that the syntax is correct.  If it
doesn't
compile, then obviously you need to fix it.  :)
I normally keep a lilypond file in ~/tmp/foo.ly so that I can quickly test
something
like this; it's quite useful.
