The package that I'm running on a similar sized 1/2A combat wing is the a 2212 - 2200 kV motor, 2 cell 1000 mah Lipo, 20 amp ESC, and a Hubin timer. This setup turns a 6-6 prop at about 15000 rpm and flies the plane easily on 35 or 42 foot lines, though it wouldn't be too competitive with even a TD powered Hacker. It's more of a sport flyer or test sled.
That motor is slightly larger than your 1408-1450 and the 1450 wouldn't do well on 2 cells, either. I would go with your 1408, 3 cell 850 or 1000 mah Lipo, your 30 ESC (which will work fine and doesn't weigh much more than a 20 amp one), probably a 7-6 prop. Expect about 12000 rpm and 10 or 12 amp draw, which would work out to about a 4 minute flight on the 1000's. You will also need some type of control line timer - I really like the Hubin's with screwdriver adjustments. I don't know for sure, but I seem to remember that the e-flites need to be reprogrammed every flight at least for flight time. The Hubin timers should be available through Brodak.
The nice thing about electrics is that they are very versatile and you can generally dial in just about any motor/prop/battery combo to at least be flyable.
