problems with lilypond

[liang seng]

To whom it may concern,
 Hi, I seem to have some problems with Lilypond. For your reference, I've 
attached the lilypond file and the pdf file with this e-mail.
The first problem is the position of the dynamic mark "p". As the p is for 
the upper voice, how do I move it to the position above the notes? Secondly, 
in the lower voice, how do I move the whole-note rest to the centre of the 
bar? I think the reason the rest is originally on the left hand side of the 
bar is because of it is a whole-note, the note would be at the left side of 
the bar. Is it possible for you to edit the lilypond file to demonstrate 
this? I tried finding the answers in the tutorial and documents, but as they 
were too large I sort of gave up.
Thank you very much.
Yours sincerely,
Seng Liang.
