I did not even see this post. paintball tournament and senior project had me busy this weekend. I hate when I miss the beginning of the thread. hard to catch up.. but I will try..
I would not worry about having rear speakers. if you do use them power them off the deck. save time and money. plus sound better.
I would stay away from alpine subs and RF. the RF amps are ok for a sub, but that is about it and there are better ones.
I think one nice sub will be plenty. it will take up less room then two weaker subs and soudn just as nice. if you are not wanting to spend alot of money then I would stick with subs that dont require alot of power. this will save money on the amp.
if you want to make it really simple you could use this amp.

you would be powering the fronts, rears, and sub off this amp. use the JL 12w3v2 sub.

this is another option. I konw this amp is expensive. I have not checked the price lately.

you could hook the sub up to channels 1 and 2 bridged for 300Wrms and hook the fronts up to channels 3 adn 4 in stereo for 75Wrms. get any sub that only requires around 300Wrms.
I will post some more ideas later if you need more.
