Placing tempo marking and instrument names

[Anna Choma]

Hello!

I have two problems:

1. How can one raise or lower the tempo marking \tempo 4 = 100 for 
example? It is too low (the first sign is a rest, the second note c'') 
and looks ugly. Which is the best way of shifting left and right 
symbols? Is there any universal way? How to use \kern or \raise in 
this context?

2. I have done a score with 14 instruments. The are many names of 
instruments, long and short. Lilypond places them aligned to left 
(raggedright, flushleft). I wanted to put them near the score, namely 
aligned to left (to score). Hown can I do it?

Bes regards,
