Look in the Template.h file that is part of the standrd project. the default values are:
#define DEVICE_WIDTH 1024
#define DEVICE_HEIGHT 768
#define DEVICE_POS_X 32
#define DEVICE_POS_Y 32
#define FULLSCREEN false
Set those to whatever you want them to be.
For the title, have a look in Core.cpp at line 791 (approx) where the window is created
HWND hWnd = CreateWindowW(L"OPENGLWINDOW", L"AGK", dwStyle, x, y, WindowRect.right-WindowRect.left, WindowRect.bottom-WindowRect.top, NULL, NULL, hInstance, NULL);
Change the L"AGK" to whatever you want it to be.
You should not then have to do any window size setting or title setting in the app
