Looks like your pads were letting the rotors' heat get into your fluid, resulting in the spongy pedal. The brake duct kit you're going to install may make a noticeable difference in how long your pads hold up.

All pads give up sooner or later, each one in its own way. Hawk's HT10s, for example, begin to break up at 1/2 thickness and should be replaced at that time. At 18mm, the OEM pads' thickness isn't very great, which doesn't help.

Too bad the AP kit isn't out yet - one of those along with a brake duct kit would erase brakes from your list of things to be concerned about.
