When I'm sitting at a stop light/sign and back pedal, the chain will slip off the biggest chainring. What do I need to adjust to fix that?

Sounds like your using the top part of the cassette ( last couple of cogs ) instead of shifting down to the inner ring , as David Millar learned that ain┤t the way to do it .
( could check chain line though , if it┤s too far to the outside that might cause something similar : length of bottom bracket )
Try lubing the freehub.
I found that when my freewheel/cassette whatever
needed to be lubed (it was quite dry) I would drop the
chain when backpedaling.

Like lotek said...check out your freehub/freewheel...I had a similar problem last summer before I just bought new wheels...the freewheel would actually stay engaged after I stopped pedaling, causin' the chain to "snap&sling"...made for problems on rooty downhills, too...
