First question:
Let's just say one of my rooms is my bedroom. In my memo some letter pairs like X,V J,G V,X G,J and lots others are very hard. thinking one up on the spot in your room is very time consuming and memo times will be alot longer. Also if I have learnt every letter conbination, one picture may not associate with my paticular room at all, but if I did every letter combination with one room. Thats very hard cause if some one has over 20 prepared rooms and they lernt every letter conbination with each room. Thats alot of conbinations.
I get a feeling that you have misunderstood something. You don't have to associate the room with pictures or words. Room is used to remember the order or the sequence of items/words.
Let's take the letters from your own post: X,V J,G V,X G,J.
Pair them up: XV JG VX GJ
(Of course they don't appear like that in a regular solve, but it does not matter).
I don't know what your word-list contains, but for this example we can use what Chris has online at http://www.speedcubing.com/chris/memo-images.html
XV - Xavier (X-men)
JG - jug
VX - vortex
GJ - Green Giant
Then in your bedroom you find 4 locations. Maybe:
1) On the bed
2) under the pillow
3) on the floor
4) in the closet
And always in the same order.
And picture this:
Xavier on the bed, jug under the pillow, vortex on the floor and green giant in the closet.
Later you just go through those locations in the same order, find the creatures and items in there and translate them back to letters and letters back to stickers on the cube.
Next time you put different things into the same locations, just the order of the locations is fixed.
