Steering rack boot torn...replace tie rods?

[Propagandhi41]

Ok my steering rack boot on the passenger side is torn. I'm not sure how long but I'm sure it's been long enough to ruin the inner tie rod. I was just going to replace the boot, but that would be stupid so I think I'm going to replace the inner tie rod, but I have a few questions:

1.) With the boot being torn would anything else except the inner tie rod be damaged

2.) And when i replace it, is it ok to replace just one side or would I have to go with both...

appreciate all the help
