This question is perhaps better suited to StackOverflow, as it doesn't specifically relate to GIS (other than that the application you're using is QGIS).

To create a new dock widget and add it to the left panel:

dockwidget = QtGui.QDockWidget(iface.mainWindow())
iface.addDockWidget(Qt.LeftDockWidgetArea, dockwidget)

If the user moves it to a floating window you can then re-dock it using setFloating:

dockwidget.setFloating(False)

If you want to prevent the user from moving it to a floating window you need to set the "features" of the widget. In the example below, the widget is movable and closable, but not floatable:

dockwidget.setFeatures(QtGui.QDockWidget.DockWidgetClosable | QtGui.QDockWidget.DockWidgetMovable)

Have a look at this:

The relevant part being:

self.dock = MyPluginDialog()
self.iface.addDockWidget( Qt.RightDockWidgetArea, self.dock )

I'll answer the question that is stated in the title.

You can use the following code to show your dialog in the bottom-left corner (do all this right before the call to self.dlg.show()):

    ph = self.dlg.parent().geometry().height()
    px = self.dlg.parent().geometry().x()
    py = self.dlg.parent().geometry().y()
    dw = self.dlg.width()
    dh = self.dlg.height()   
    self.dlg.setGeometry( px, py+ph-dh, dw, dh )

If you want your dialog at the top-left corner, change the second parameter of setGeometry() to py.

As for your second question, I cannot replicate that. Have a look at my plugin Synchronize QGIS with a directory, the dialog is not hidden when I interact with the map via map tools.

By the way, you should really ask a single question per post. Otherwise you discourage people to answer your questions.
