I would say keep it simple.
3250DVD has decent SQ and also has the DLPs (Digital Listening Position Selector). To get away with the localization without TA, i would look for components which have some flexible adjustments in passive crossover.
Deaden the doors enough so the mid bass drivers can play low enough to keep the frequency spectrum in the the lime if you don't want to add a sub. And aim the tweets tweaked by crossover and angles to give you a nice vocal centre.
I won't suggest the SR4 amp, once they go into fault state with red light blinking, you will get into trouble and to your surprise, they are impossible to repair.
K6, PS, are good choices pair them with Class AB and you should be pretty golden.
EDIT: And as yawar bhai and maddy bhai suggested, forget the rears...forever
