Chris,
This is probably the most useful links about hints: http://jonathanlewis.wordpress.com/2008/05/02/rules-for-hinting/.
This is a position I share. I used to think that a few hints were
harmless, but I'm no longer so sure.
A few weeks ago, I met an interesting query in which the hint was
contributing to get the proper result (by forcing an index descent). In
other words: remove the hint, you get a wrong result. Isn't it nice?
