Hi,

your first problem is an internal problem of the FrontEnd.
Because the FrontEnd use in may cases expressions that are
broken into manual placed boxes it must force TeX to do the 
same. But TeX don't like such placements with explicit 
horizontal and vertical skips. I don't believe that 
a TeX output that is readable *and* look almost perfect in
the dvi-file is possible with the FrontEnd. The best solution
to avoid the explicit placements is to typeset the input
in an alltt-environment and switch to the math-mode when a non-space
charackter begins. But that needs a complete rewritten TeXSave[]
command.

Your second problems is simple. TeXSave[] generate \frac's when
it finds a FractionBox[] and 
FractionBox[a,b]  is transformed into \frac{a}{b}
while a/b is left unchanged. 

I have written a TeX-FrontEnd that read a (allmost) 
TeX file it looks for
special Mathematica input-environemtns. The contents of this 
input-environments
send to the Mathematica kernel and the TeXForm of the result 
is inserted into the output file. If you like the idea
I can send you the program, the style files and all the other
stuff. It's perfect for processing books, manuals with Manthematica
input.

Regards
  Jens
