Can it come back to life after being rootbound and frozen? So far, I've thawed it with water, replanted it in a bigger pot, and cut all the dead limbs off. Does it have a chance?
Yes, your tree has a chance to come back, as long as some part of the plant is alive. Here's how to check whether the remaining parts of the trunk are alive:

Even if the aboveground parts are all dead, you can cut the tree off at the base, and it might regrow from the roots. Make sure not to overwater it (only water when the soil is dry about an inch down), because damaged plants use less water.
I have a beautiful rubber tree that just keeps growing. My issue is that it is getting too tall for my house. What can I do? Can I cut it off?
Yes, you can prune your plant.

I just bought a new smaller rubber tree plant at Walmart and I have taken it out of the old pot,removed the old soil and loosened the roots.,repoted it in a slightly larger pot with fresh Hyponex soil.I cleaned the leaves and placed it under a south window in the bedroom it has lots of bright indirect light.Should I move it up higher more towards the window?
The plant should be at the same height as the window if possible.

I have repotted my plant and now it's leaves are growing a lot smaller and slower.
It is common for a Rubber Tree plant to go though a bit of transplant shock. Place the plant in the same location and water the same.
A light fertilizer feeding can help.

When pruning a rubber tree, what do I do to the branch that will be leaking milk? How do I cover that without damaging the tree?
The sap will stop on it's own. This sap can cause skin irritation so avoid touching it.
Hi I just moved and I have a good sized potted rubber tree.at my old location I kept it on my porch during the summer where it didn't get any direct sunlight. I'd like to put it on my patio at this new location but the patio gets about 3 to 4 hours of direct sunlight then the rest if the day in shade. Is that to much direct sunlight for my plant? Thanks...Nick
Nick- It depends a little on your new location. In warm coastal areas Ficus elastica (rubber tree plant) will tolerate more sun than in hotter inland areas. If the plant is going to be in direct sunlight, early morning exposure would be best, but I have seen this plant growing in full sun in Southern California. Since it is in a pot acclimate the plant to the sun exposure gradually if possible. Avoid introducing the plant to sun on a very hot day.
When pruning a rubber tree do I need to protect the remaining stem as it exudes milk?
No, the sap will stop on it's own.
