a little tip from me, the setting i usually use for indoor is TV coz i'll set it to 1/60 or 1/100 and let the aperture run itself, at least at this setting ur picture won't be blur coz of movement.ISO will set at 200-400 depends how much light u need. even sometime a picture with noise is better than a blur picture. another way is setting low ISO and play with exposure maybe +1, need to play around with it.

as for AV i will usually use for outdoor, the light that comes in doesn't matter anymore on outdoor coz the shutter speed will always be set high and the picture won't be blur.here can adjust ur aperture to your need, blur background or flat picture. as for ISO usually i will set 100 - 200. this also depends if ur under a tent it will be darker so 400 is still ok.

hope this helps!
