[racket] scribbling newbie questions

Inspired by  <http://www.infoq.com/presentations/Racket>
http://www.infoq.com/presentations/Racket and now that DrRacket shows the
'Scribble HTML' button, I do my first serious attempt to scribble. With this
button I can easily see what I get. I use it very frequently. Marvelous! I
use scribble/manual. But of course, even after long searches in the docs (I
am a bad scribbler and a bad browser), I have some questions.
 
Q1
@racket[(string-length ((fmt "I") #e1e100000))]
is expanded to
(string-length ((fmt "I") 1000....000))
with 100000 zeros. How can I make scribble render #e1e100000 as #e1e100000?
 
Q2
I use verbatim to escape interpretation, but this function always produces a
separate line. Is there something like verbatim that I can use within a
paragraph? For example to include character @ and unbalanced parentheses and
brackets in plain text.
 
Q3
I try
@tabular[#:sep @hspace[3] #:style 'top (list (list ....]
in an attempt to have each element justified at top, but this does no show
any effect. How can I outline like in:
 
item1   this is item-1
        Not important.
 
item2   this is item-2
        not important either.
 
item3   end
        of this
        question.
 
Thanks for the marvelous Scribble!
