Generally speaking, paragraph breaking is controlled by a few
registers, the most important is \tolerance. \sloppy sets \tolerance
to 10000 which then looks ugly. You should start with \tolerance=9999.
In such a case you should not have overfull boxes (if you still have
them, some changes in the text may be needed). After this run you find
the highest badness of the underfull box. Set \tolerance to this value
and \hbadness to one less and run LaTeX again. You should see just one
underfull box in your log. Now you can decrease \tolerance (and
badness) until you get an overfull box, then return to the higher
value of \tolerance and set \hbadness to the same value. If you have a
paragraph with an overfull box, then set locally for  that paragraph
\emergencystretch=1em. (This algorithm appeared years ago in an
article by Phil Taylor and I use it since then)
