I ride a Pista, an '05. I dunno about the Tempo, that wasn't around until recently, you could also conside the Potenza if you are feeling flush (this used to be called the Pista EOM but was re-branded last year) its a bit lighter and a lot stiffer.
The stock build for a pista has Mavic CXP22 wheels, so you should consider allowing for an upgrade to CXP33s or OpenPro's (I went for OpenPro's). The Condor Selle Italia saddle is like sitting on an RSJ, so allow for a saddle upgrade to (I'd go for whatever you have found comfortable in the past).
As for ratios, its a personal thing. What are your habits on a geared bike, are you a grinder or a spinner? Something in the low 70's is a good starting point, but new cogs are cheap, so you can experiment (a flip flop hub helps here) - although if you make big changes you'll need to adjust your chain length. I wouldn't go above 80 inches unless you have thighs like Marrows, and lower than 68 will have you spinning like a mofo (or like hippy) on the down hill stretches.
Try and go to Condor when they are not busy as you'll get better service. They've got a measuring rig and can sort you out for frame size and stem length etc.
Oh, and don't buy one from Halfords Bike Hut, as they will just sell you a stock bike with no chance to upgrade at marginal cost
