When you replaced the pads, did you remove the cap from the brake fluid resevrior before you pushed the cylinders in the calipers back? I have heard that not doing so can cause problems with brake functionallity. If the caliper is busted, the repair kits aren't too expensive or difficult to replace. You can get all the parts needed to completely rebuild the caliper for about $45 from Rock Auto. Or a complete refurb caliper for $70.89. $35 of that you get back as a core return.
I would start by redoing the brake pad install on the driver side to make sure the pad is seated correctly. After that, try pressing and releasing the brake. Then see if you can turn the rotor by hand. If you can't turn it, you may need to replace the caliper.
