Hi,
Here is what I have. You can see 4 base layers, and start of overlays at
end. Any of the 3 base layers Google, TMS, WMS selected will cause
overlay TMS to be displayed properly. Selecting OSM base layer selects
tiles with wrong zoom.
With OSM as base layer it is incorrectly selecting tile such as this
with zoom 10, which is 6 too large

It should be asking for

//////Base Layers
var gphy = new OpenLayers.Layer.Google("Google Physical", {
type: google.maps.MapTypeId.TERRAIN,
MAX_ZOOM_LEVEL: 12,
MIN_ZOOM_LEVEL: 6,
displayInLayerSwitcher: false,
visibility: false,
buffer: 0
});
var osm = new OpenLayers.Layer.OSM("Open Street Map");
var counties_base = new OpenLayers.Layer.TMS("None",
SERVER_URI + "tilecache/", {
layername: "counties",
type: "png",
tileOrigin: new OpenLayers.LonLat(-9462455, 3963396)
}
);
var hillshade = new OpenLayers.Layer.WMS("NC Hillshade",
SERVER_URI + "geoserver/wms", {
layers: "NC_Hill_3857_to",
format: 'image/png'
}, {
visibility: false,
displayInLayerSwitcher: false
});

How are you creating the TMS layer? Are you using an OSM layer with the
TMS urls? If so that is you problem, TMS and OSM use opposite y dimension
mappings. Use a TMS layer instead.

Someone pointed out that I could request tiles from tilecache using TMS
instead of WMS, which I have done and it has mostly fixed my problems.
However, if I use Open Street Map as my base layer then my TMS overlays
are requesting the wrong tiles.
If I don't get any suggestions from the list I am going to file a bug.

Is the baselayer you are trying to serve from WMS in 900913? Serving
from tilecache is only going to work if the tiles are in right project.
Try losing the tileorigin in the constructor as well.
