There are a number of conversations that work some ideas about body cues...
Here are a few to get you started!
Josepha has some great directions here, in a discussion about her 5 Steps for Natural Academic Riding Art: viewtopic.php?f=9&t=2019
Here's one on leg placement/pelvis and body cues:viewtopic.php?f=9&t=2019
And here's a great one on Centered Riding:viewtopic.php?f=9&t=1748
Here's one on using your body/weight as a cue for the halt:viewtopic.php?f=9&t=1254
And there are some great ideas, approaches, nuggets of wonderful information tucked in various people's diaries -- the first one that's occuring to me is Sue's (windhorsesue):viewtopic.php?f=5&t=237
And I'm with you on that totally naked dream!
