yeah, I did brakes and rotors all the way around when I bought truck and all fluids except brake/ps and I had that "spongy" brake feeling. I knew I seated the pads right and I even use a air polisher to clean corrosion off the brackets before I put new pads in. Hopefully this will take care of it!
You may also want to replace the rubber flex lines if they are old/cracked as they tend to get more spongy over time. If you do the brake bleeding, then if you have access to compressed air you can make a very cheap power bleeder that works great. Make sure to use no more than 10-15 psi max and don't let the master cylinder run out of brake fluid.
Here's the DIY power bleeder (works great!): Brake Bleeder - a set on Flickr
