For 5.1 setup, generally speakers are placed on the side with 90-110 degree angle in to main listening position.
If possible, use some make shift arrangement to place speakers at different height and see what works best for you. As I mentioned earlier, I use a stand which is about 43-44" (I think it can be increased another 2-3", if needed) and 150s are placed on top of it, so total height from floor to top of the speaker is about 56-57". If that works for you, that stand was something like $45, when I got it.
Putting these on back wall perhaps not a good idea for 5.1 setup, but if it works for you nothing wrong with that too.
