Answer 1

edit:

Changed the braced iterators, good call. Also, call this function with a reverse iterator.

You can probably do something like this:

#!/bin/bash
HISTFILE=~/.bash_history   # if you are running it in a 
                           # non interactive shell history would not work else
set -o history
for i in `seq $1 $2`;
do
    history -d $i
done
history -w

Where you will evoke like this:

./nameOfYourScript 563 514

Notice I haven't put any error checking in for the bounds. I'll leave that as an exercise to the reader.
