If you have more than one GeoTIFF, you can mosaic them before the conversion. For instance, you can make a virtual mosaic from all of them contained in the same directory: gdalbuildvrt mosaic.vrt *.tif
The coordinates of the target extent have to be expressed in the target SRS: -te xmin ymin xmax ymax: set georeferenced extents of output file to be created (in target SRS). Being... >cs2cs +init=EPSG:4326 +to +init=EPSG:3857 5 43 556597.45 5311971.85 0.00 15 48 1669792.36 6106854.83 0.00 the command should be something like: ...
the -te flag expects the coordinates to be projected in the -t_srs CRS. EPSG:3857 has as a unit meters, and your inputs are most likely degrees. to obtain the correct values gdalwarp needs you can project from one coordinate system to antoher using the cs2cs program: cs2cs +init=epsg:4326 +to +init=epsg:3857 The default order of values are x-y or E-N
And be sure to use -co "TILED=YES" to be able to compress huge files with jpeg, since jpeg only allows small images. (We speak about some thousand pixels per dimension...)
In Tilestache you specify the following array of resolution in the projection object: [5545984, 2772992, 1386496, 693248, 346624, 173312, 86656, 43328, 21664, 10832, 5416, 2708, 1354, 677, 338.5, 169.25, 84.625, 42.3125, 21.15625, 10.578125, 5.2890625, 1] You told us that you are using the same resolutions as link #2 which are: [234.375, 117.1875, ...
