Notation question

[Stan Mulder]

I'm new to the list and I'm trying to get my lyrics (percussion sticking 
in this case) above the beams instead of below the noteheads. I've 
fiddled around with "context" but I'm lost. Code is below.

I also noticed that my grace notes (grace note on the flams) were the 
same size as the regular notes. What gives? They should be smaller than 
the main note.

Any suggestions for simplification is appreciated.

Regards,
Stan
