The front and rear speakers are around 11 pounds, the center is 19lbs, the center has key hole slots on the back of it, not sure if the book shelves do or not, I can look tonight when I get home. You also have the option to order the bipole surrounds for more. I would maybe consider this if you are putting the speakers to the side in a longer room, if they are behind you not sure it will be worth the money. Not sure how you would mount on the wall you could use a drywall tapcon as they hold 50 plus lbs, good thing about these speakers is that they are not ported in the rear as some speakers are so you will not interfere with their sound by mounting right up to a wall. Are you going to run the speaker wire through the walls? You might want to consider how you do that.
For my bedroom, I have them on bookshelves and the center on the entertainment unit, the rears I wired using white flatwire attached to the baseboards. You can't tell it's there but it's a pain in the butt to work with. Wish it stuck better. All in all it was a good solution for not having to get up in the attic though. May depend on your floor layout though.

If you are pulling through walls and ceilings or can hide under carpet then it's a non-issue. As for receivers you will have to decide what features you want, iphone compatible, how many HDMI inputs you will need, do you need a GUI. I have two pioneer receivers one in the bedroom and one in the living room. I like them both, both have built in Ipod capability and include the cable...however in hindsight I wish they were in the back so it looked cleaner. So I might start looking for a wireless ipod dock for that reason. They also have there own built in speaker calibration system which is nice as well. (MCACC)
Pioneer, Onkyo and Yamaha make good receivers...of late have heard that Denon is having quality issues. Of course this is my two cents so others may chime in otherwise.
