Chris -- I passed the resolutions array to TileCache but I get pink tiles when the layer is turned on outside the boundaries of the resolutions array. The layer does render properly when zoomed in at the supported resolution. My units are decimal degrees, and my TileCache layer looks like so.
I'm scratching my head on this one...

It's not clear to me what your units, maxExtent, etc. are. You should set your TileCache layer up to have the *resolutions of the base layer* which exist between those scales. OpenLayers.Util.getResolutionFromScale may be useful.
