This is an incredibly done first image - I would guess you've got some rendering experience in other render packages?
Render settings: Easy 9 at 235 passes.
I have two specific questions:
1) To the right of the fire place there is picture frame hanging on the wall. Why are the images ("pictures") in the frame not visible? (refer to the attached SU image and you can see I have inserted images as textures into the frame; but they don't seem to render for some reason.)
2) I am using ies files for the recessed lighting in the ceiling. The efficiency is set to 100% and the Power to 1.0 for those lights. However, after I began using the ies files in the ceiling the rendered image seemed too dark. So I find myself adjusting the exposure up to as much as 2.00.
a. Is that too much of an adjustment for exposure?
This sounds correct. good work.
b. What would be considered too much of an exposer adjustment?
Using a computer with a calibrated monitor is important. Then, adjust exposure up until the lightest area is juuuuuust washed out... then back off the exposure a step.
c. Should I never adjust the Power or Efficiency of ies lighting?
Never is a strong word. An artist should start as you've done by using the tool properly. If it is desired you can change the power of the ies light, but realize that is probably going to effect the light possibly in a negative way by making it too bright or too dim in comparison to real world situations... but if that's not important, then feel free to adjust the power of ies lights. Avoid making lights too bright, it will increase render times and increase rendering artifacts. You've done right by adjusting exposure just as a real camera does in order to compensate for the low lighting.
Note: FWIW The floor lamps along the back wall are the only two lights in that area (the overhead lights are off in the back of the image.)
I would turn them on. in arch. magazine images, they turn all the lights on and even add some cleverly hidden artistic fill lights... you can do the same if you wish.
