Does it sound like I need to rebuild my calipers???

I have noticed that it feels as if my calipers/brake pads are grabbing at least one of my brake rotors. On slight inclines my car just doesn't seem to roll real easily. I also noticed that when I took my car into Andial recently for an MFI adjustment, they indicated that "brakes are hanging up and not releasing right away"

So I jacked the car up tonight and it felt like the rear wheels were not rotating completely free of the calipers/brake pads. Am I right to assume that it might be time for caliper rebuild kits? Is it possibly something else that I haven't considered?

Lastly, if I rebuild the calipers, what else should I do at the same time besides rotors, pads and flushing the brake fluid?

Any Orange County wrenches out there who might want to check over my shoulder as I complete this DIY project??? I feel as though I can do it myself, but given that I'm talking about the brakes, I'd like to have somebody watch me put it all back together to make sure that I don't screw it up. I pay in beer and fine wine! Best regards to all!

you might need new flex lines also. brakes are not hard, just nasty. clean everything before you start. only do one side at a time so you have a reference.
