Congratulations for not following typical audio herd mentality and choosing something you feel will deliver music. They will!
First rule: NO RULES!
Distance from the rear wall will depend on where you find your preferred listening position after experimentation, where the speaker ends up to get the best bass in your room, how far apart you can get away with and still like the imaging, and other sonic factors you note.
Start with the speakers where ever you want, you'll be moving them anyway just to test your reaction to the sound at different positions. Start with your last speakers were, but do not be afraid to move them around, marking each position and making notes about how you felt about the sound in that position.
Remember, the woofers will change a lot during break-in, so you might have to revisit prior positions. Likely you will very quickly find sonically "acceptable" positions quickly, so you will be enjoying music while testing the different possible positions. Don't rush it, enjoy the sound and don't be afraid to leave them in acceptable positions for a few days before you go onto the next location. This will make differences easier to hear.
Don't forget toe in: you can tune the upper end this way. If they are too soft aim them more at your ears, if they are too present toe them out so they fire at a position behind you.
Enjoy!
