Moving the working camera in Blender and Wings is pretty much the same.  In blender, hold down the middle mouse button (or Alt and the left button) and move the mouse to move the view.  Use the scroll wheel or hold Alt, Ctrl and the left mouse button and move the mouse to zoom.  Hold shift and the middle mouse button or alt and shift and the left mouse button to pan.

That just moves the working view, the camera that you render from remains stationary.  You can move that like any other object in the scene, or you can make it come to where your working view is with Ctrl+Alt+numpad 0.  You can also look through the camera with numpad 0, then select it (right click on the outer, solid box), and move it with the g key to pan, g followed by a middle mouse click to move in and out, r to rotate or r followed by a middle mouse click to rotate in 3d (this will rotate around whatever rotation center you have set, and it's most useful if you are rotating around the cursor.  You can move the cursor to the current object and rotate the camera around the cursor, effectively rotating it around the object.  Let me know if you want further explanation of that.)

In wings, I believe you click the middle mouse button, release it, move the mouse to move the camera, then click the middle button again.  You can zoom with the scroll wheel.  I forget the shortcut keys and how to pan, though.

Is V4 an obj?  I haven't tried it with that one, but this works for other poser figures.  If you go to file->import->wavefront obj then find the v4 obj file on your hard drive, click the filename and then the import button in the top right, then hit ok or whatever it is in the little options dialog it should get imported.  Be careful not to let your mouse move outside the options dialog or it may just disappear and not import anything.
