Outfitting a house with speakers in every room- any tips or advice?

So, my brother is building a house and wants to put in-wall speakers all over the place, but he doesn't know anything about purchasing speakers. The guys who will be doing the electrical work and cutting the drywall have recommended this setup for him:

Speakercraft Aim7 $400 per pair - kitchen, master bedroom, office, garage, rear surround
Speakercraft Aim5 $300 per pair - laundry room and all bed rooms that are not one the zone system
Speakercraft OE6One $550 per pair - patio - weatherproof
Speakercraft in room 10" Subwoofer $600
Speakercraft Cinemastick soundbar speaker for front Channels $800

Total speaker cost: $5150.00 including surround sound speakers

He showed these recommendations to me and I thought that it would be prudent to ask some of you fine gentlemen and ladies for your thoughts on this brand (Speakercraft) and this setup.

This particular shopping list is a little out of his price range, so his plan B was going to ultimate electronics and picking up whatever they reccomend. I think that he can do better than that. Any thoughts?

What I am looking for is
1. Some reputable sites that with good reviews/information (I checked consumer reports and their section on speakers is pretty pathetic.)
2. Any tips from people who have attempted something like this in the past.
3. Specific Speaker recommendations for:
2.0 In wall speakers $200-350
2.0 In ceiling speakers $200-350
5.1 system under $1500
2.0 Weatherproof outside speakers $400-550

Thanks everyone for reading my post!

Ok guys, I can't thank you enough for all of the feedback! These posts have really shaken my brother up and they are getting him to consider other options. He has been persuaded to focus on the 5.1, kitchen/dining room, and patio for now and will install/purchase the rest later when he has the money.

To answer a few of the questions posed:

His living room (where he wants to put in the 5.1) is 2187 cubic feet, but it is open in back with a kitchen/dining area behind it for a total of 5670 cubic feet.

He has multiple cat 5 or 6 wires as well as audio cords going to each room. (he also has redundancy in case of an issue later on)

He is planning on having the main floor and downstairs be on one zone (I think that is what it is called.) That includes the kitchen/dining room, entertainment room, living room (5.1), patio, laundry room. He wants them to be able to uses different sources. As for the upstairs there are control panels in each bedroom. I am not exactly sure on the details, but he has discussed them with a friend (the pro who wants him to use speakercraft.)

I don't think he had any idea about the necessity for an amp nor the cost of a whole house audio system so cheers for the heads-up on those issues.

His budget for the much alluded to nebulous 5.1 system is being upped from 1.5k to +3k and I am glad to have learned that I we should avoid in-wall/in-ceiling speakers for that system.

This weekend we are going to try and get out and listen to some speakers. Are there any other specific models or vendors you guys recommend for:

5.1 system (I guess it could be 7.1 if that is 'better') $3,000 Also, is the cinema-stick a good idea for this setup?
2.0 Weatherproof outside speakers $400-550
2.0 In wall speakers for the kitchen/dining room $400-450

Lastly, I would like to add that my brother is a recent college grad with humble tastes when it comes to speakers. We aren't audiophiles (yet) but we are music nuts! Up until now we have gotten by with logitech Z-2300's and sennheiser hd-600's, but he is looking for a significant upgrade...

Once again thank you all so much for your patience and expertise. I am confident that your responses have helped us out immeasurably!
