The only way to start the map at a certain scale or location is to set the startExtent in the constructor parameters.  Alternatively you can hide the map, zoom to the scale and then show it.

The zoom slider has to be hidden after the map is loaded if you use the slider:true constructor parameter.  slider:false will not allow you to show the slider at all once the map is created.  The only alternative is to create your own slider and connect it to the maps onChangeExtent event.

andrew is right. you can also add an onload event that fires after the map loads, which you can then execute your code below.

mapCenterPoint=map.extent.getCenter();
map.centerAndZoom(mapCenterPoint,scaleDegry);
map.resize();
