It sounds like your father has a pretty good idea what he wants.
I think your best bet would be to make contact with a dealer/installer in your area that can come to his home and show him some higher-quality alternatives to the crappy overpriced Bose system.
What total price are you talking about? The details are a bit sketchy for anyone to get specific about recommendations.
KEF and PSB are companies that have good speakers for wall installation, as does JBL (see their L820 and L810).
Wall-mounted speakers generally perform better than in-wall speakers.
Denon receivers are very good and if you look at the features on the models on their website you can sort out which you need.
