Poison ivy is a tough customer and trying to kill it with salt would take so much that it would leave the soils around it in bad shape for a long while and leech out in the soils badly. I know it is more expensive, but using the brush killing herbicides really is the way to go. You get a more centralized kill of what you really want to kill, down to the root zone. Getting it killed deep into the root zone is what is needed as otherwise it will come up with vigor in even more areas than it is currently a problem in.

The sap itself should be fine. However, you may want to use gloves and other protective clothing when working around or cutting the tree as a precaution. If the plant has directly come into contact with the tree, then the oils from the poison ivy could be passed on to you when touching it.

If you're looking to get rid of poison ivy (or oak), treat with herbicide first (to kill the roots) then, wearing gloves, hand pull dead plant material and dispose of it. Do not burn it, however, as the poison can be breathed in and will result in a nasty rash.

No. While these plants do go dormant in fall and winter, be aware that they can still cause problems. The poison remains active even after the plant is dead. So even if you think it's dead, you can still get a rash from contact with the plant.
