What is SAVED and when?

In FSX with Accelerator, but using FSUIPC4 for some things.

I have been trying to get some things set right for a while now. And I am getting close but I am confused by some things still.

1. Sometimes when I open FSX and Fly Now, the monitors are set as I had them previously; One view on left monitor, and several views in the right.  But often they are all lapped on top of one another in the left.

2. I am working with getting my rate of roll better on the 172 (only thing I fly) so many changes in FSUIPC and FSX controls.

3. I save things in both menus... options and File, hoping to hold onto the things I want.  Seems to work sometimes but not others.

4. I often save positions in my flights to come back to, but sometimes I go to the saved final approach BUT the controller changes I made are lost.

Of all of these, I wonder:

What is the difference between the two saves, one in File menu, and one in Options menu?

How does one save controller changes done in FSX? and in FSUIPC?

How does one save the flight position?

Does the save for flight position also save the controller info and monitor settings of Views?

Thanx!

All of the help I have gotten here has gotten me closer, but it would have been better to have not had to learn how to do all of these configs for my purposes.  Almost there though!
