Hi I have long torso / short leg proportions also, it's not uncommon; couple of points to mention; is the standover height you quoted in bare feet of wearing shoes with your cleats? that will make a difference, clearly. You can compensate for reach using a combination of stem length and seatpost setback; also , some saddles will have shorter adjustable area on the rails, so pick something you know you can move back as far as possible without hitting the bend on the rail, a lot depends on the seatpost angle here so I would really recommend a bike fit and advice on frame geometry prior to busting open the piggy-bank!
Careful with the stem and layback option. A long stem will make your steering a bit on the slow and floppy side. Moving the seat back effectively slackens your seatpost angle which will not only tighten your hip angle but reduce the efficiency of your pedalling. Remember, over the bracket is faster. So both together is not ideal, but one or the other is a disaster. No only do you suffer from the problems I've mentioned, but your weight will be distributed all wrong which will do the handling a whole lot of no good.
