A tower speaker will most often play lower than a bookshelf speaker. The extra woofers and larger cabinet create better extension. When you have a receiver and a sub woofer, your receiver will set a crossover point, usually 80Hz, and at this point the AVR rolls off the frequencies to the speakers and sends them to the sub. Your sub is better at handling those low frequencies than a tower speaker is. Since both your bookshelf and tower can play down below that crossover point without any trouble, you end up not needing the extra extension from the tower, since the sub is taking care of that. If you have $500 for a speaker, you can get a nicer bookshelf than you can a tower, and since most everyone already has a sub, you can get more bang for your buck this way.
Going with R series bookshelves over the Q series towers, lets you get a better speaker for close to the same money, and end up with better sound.
As for a receiver, unless you plan to blast the speakers, most every respectable receiver will work fine. I prefer Denon, but Pioneer and Yamaha are also good options. Emotiva recently released their own AVR, but I do not know if they will ship there.
Offhand I do not know who ships to Dubai, the big ID companies in the US are SVS, HSU, PSA, Outlaw, and Rythmik.
