Jamal, The tiling scheme is a group of configuration settings that include the scale levels, point of origin, coordinate system, and image format of the cache tiles. These properties define where cache tile boundaries will exist and are important to match when overlaying caches in some clients. Other properties, such as image format and antialiasing, are also written into the tiling scheme. ArcGIS Online tiling scheme has 20 scales (levels of details); however, on the Caching tab of your Service Editor window, in the Levels of Detail panel, you have chosen to cache only the scales between 10 and 17. So when you go to the Advanced tab, you can see that those scales that are not within 10-17 range will be greyed out to indicate that the cache tiles will not be created in those scales. However, it is important to show them in the list - the scales will be present in the scheme even if you don't create cache tiles for them. This is done to let you cache a map service in some of the other scales later on yet preserving all other tiling scheme settings.

Jamal, When publishing a cached service, ArcGIS returns a warning message box when the estimated cache exceeds a given size. The 500MB you see is a default value which ArcMap sharing settings have been set for. This value is just something to make you aware of when you start caching perhaps because you have not planned to cache the map in all scales but forgot to deselect the certain ones. This value can be accessed from the ArcMap > Customize menu > Sharing tab. You can change the threshold for the warning by entering a new size. If you do not want the warning message to appear, uncheck Show warning when cache exceeds. The Estimated Cache Size estimate, displayed on the Caching tab of the Service Editor dialog box, is a very rough approximation based on average tile sizes for the image format you chose and the number of tiles expected in your cache. The estimate assumes a vector map for non-JPEG image formats and raster imagery for JPEG and MIXED formats. For JPEG and MIXED formats, the estimate assumes a compression quality of 75. Some deviation of the cache size is acceptable and this is something you should be aware of, so what you've shown on the screenshot is not wrong (several MBs difference is a very good estimation for ~800MB cache). When deriving estimates when your area of interest is a feature class, it???s important to note that the estimates only reflect rectangular map extents. If you specified a feature class as the area of interest for your cache, the estimate is based on the rectangular bounding box of each polygon in the feature class, not the exact feature class boundary. If you're going to cache an irregularly-shaped geographic feature, you may get a more accurate estimate by clipping a grid to the boundary of your feature class, effectively breaking up your feature into large grid cells. You can use the Create Fishnet tool to make a grid. ... View more

Jamal, the Generate Map Server Cache Tiling Scheme (Server) tool does not need to have the area of interest parameter because it is served for another purposes - to generate an XML tiling scheme file that defines the scale levels, tile dimensions, and other properties for a map service cache. This schema can be used thereafter by other map services. When you want to limit what area of your map service will be cached, you use another tool - Manage Map Server Cache Tiles (Server). This is how the software is designed. ... View more

Brad, I am not 100% sure about this, but it might be that you would have to update the title in the .mxd document and republish the map service by overwriting an existing one to get the title updated. I can't see any other way to get hands at the Title under the Document Info section. In the parameters list of the Service, there is no Title or anything close to that... http://resources.arcgis.com/en/help/server-admin-api/createService.html#params ... View more
