Rich and Lacey,
It sounds like these two have severe metabolic bone diesease. I think you guys are on the right track, but the more sicker of the two if not both should be seen by a vet because when the hypocalcemia is as severe as it sounds, calcium gluconate injections and many times vitamin D injections are required to get them back to normal levels.
It is also important to be extremely careful when handling them because their bones are probably extremely brittle and ones that are not already broken could do so very easily. It is probably advisable to take branches, trees and vines away for now and keep them confined to small cages. When they are weak they have a harder time climbing and if they fall they could injure themselves very severely in this state.
You are right on getting them under UVB lights and putting them outside in the sun. This will help them to get additional vitamin D so they can absorb the calcium. A calcium product that is recommended for this type of situation is called calcium glubionate trade named Neo-Calglucon syrup and is made by Sandoz Pharmaceuticals out of East Hanover, NJ. This product should be administered orally at 1ml per kg of body weight every 12 hours. This is only advisable if they are able to take things in orally and swallow, otherwise you risk accidentally getting into their lungs, which is also very bad. Again, it is really best to have a vet involved with this as well because blood calcium levels should be monitored to make sure that the correct levels are being reached.
If you can not force feed the sicker of the two, tube feeding may be necessary also to keep it from starving to death. This should only be attempted by a veterinarian because it is very easy to accidentally put the tube down the airway instead of the esophagus and obviously this would be very bad. Do you know how old these chams are? When they are young and supposed to be growing they need to eat about 8-12 insects per day (appropriately sized, of course).
Good job with the water, too. It would be really sad to have them die of dehydration after all the work to fix the other problems! It is important to realise, however, that if they have been neglected for a long time, they may already be in kidney failure. This happens when they are chronically dehydrated. Kidney failure is an irreversible and fatal problem, so this may be something you want to know sooner rather than later. This can be diagnosed by blood tests and some times radiographs as well.
Spinal injuries are also commonly seen with MBD. This may be something to look for too, because depending on the severity, these may not have a good outcome. This is usually diagnosed by neurologic exam, radiographs, and physical exam.
As far as antibiotics go, I would use caution. If there is infection, than obviously antibiotic treatment is warrented. Baytril is a great antibiotic, but is also an extremely powerful one and is usually reserved for bacterial infections that are resistant to some of the others and involve specific kinds of bacteria. I'm not sure if you can find them from sources other than a vet (this shouldn't happen because it is illegal, but you never know). It is very dangerous to administer antibiotics with out specific instructions because they are easily overdosed and not all antibiotics are safe in every species. Again, this is something that should be evaluated by a veterinarian and perscribed only if necessary.
As far as what to expect for prognosis, it probably depends on how bad and how long they have had problems. If they do survive, you should see them regaining strength (ability to hold themselves up and move around more easily and quickly) another sign that they are doing better is that they would start showing more interest in food and be eating on their own. Some of the bone changes that you see like the bending of the legs and jaw changes (if they have this too) probably won't return to normal, but the bones will become stronger and fractures will heal. It does take months for them to return to normal, so you have to be ready for a long commitment.
To find a good exotics vet, try this website
http://www.fvma.com/displaycommon.cfm?an=1&subarticlenbr=21 This is on the website for the Florida Veterinary Medical Association. You can search by zip code and type of vet you are looking for (exotics). I am sure there are many exotics vets in Florida because I know this state is a popular place to keep reptiles and other exotic animals.
Good luck to you!
