I'd consider getting some type of locking wheel skewers that replace the quick releases on the wheels and seatpost binder bolt. Preferably, ones that also replace the bolt in the fork as well. A good brand is Pitlocks, which are sold from urbanbiketech.com or Peter White Cycles. With these, you can use the Evolution lock around the frame (or the rear wheel as per Sheldon Brown's method), and do away with the cable lock altogether.
