The correct method for locking a bike is to put the u-lock around the rear wheel, just behind the seatpost. Your Fahgettaboudit u-lock should fit around your rear wheel without any problem.
Pick a REAL pole to lock to. I prefer parking meter poles set in concrete. Most crooks know that messing with the city's property is a whole 'nother sort of trouble, compared to breaking some store's flimsy $50 bike rack. Park in busy, well-lighted areas, with lots of people walking by. Locations with lots of bikes are ideal. Half of those bikes will have only a cable lock, so a crook will have no need to look at a bike that has a real lock.
Use the second lock to secure the front wheel to the downtube. I also replace the quick releases with bolt-on skewers.
