You might also wish (if you have extra unassigned buttons and switches in your yoke or joystick) to add some buttons to move your view up/down, left/right, front/back.  Or, pick up a TrackIR4 Pro.  This is a head tracking device which is really a "must-have" for VC users.  It allows you to look around the cockpit with a minimum of effort and in a very natural way, by simply moving your head around.

Also, if you're not already aware, if you hold down the space bar, you enter "Mouse Look" mode in FSX, and you can then use the mouse to look around the cockpit, and the scroll wheel becomes a zoom in/zoom out.   I find when I'm zoomed very far out, it is hard to read the PFD's and EICAS/EFIS screens.  You can click inside each of those display screens and a large version will "pop out" for clear view.  Click in it again to make it go away.
