Brystons love Maggies. Personally, I'd buy 2 of the Bryston Pro Pak 500 watt mono plate amps and mount them to the back of the Maggies. Forget speaker cables, and just run long ICs.
As for the rack thing: I used to do that back in the day (mid 80s to mid 90s) both for audio and HT, but it can be a hassle, unless you take Barry's advice (but then the use of a NAB-type rack becomes moot) It is definitely hard on equipment cosmetics, and unless you use insulating washers on all mounting holes, tying all the chassis together electrically can cause major ground loop problems unless you are able to connect everything together using balanced (XLR) interconnects.
