Yep, usually I put it in at the same time I add whirlfloc and some late hops (if any) - aiming for 10-15 mins before the end of the boil. It's easier than using sanitizer, and does a better job.
I don't think I've ever seen anyone use zip ties on an immersion chiller. I would not use zip ties on any part that will be touching the wort (or anywhere, for that matter, since the outlet tube of the IC will be extremely hot as well) unless you know that the plastic they are made of is safe at boiling temps. If you need to secure the coils in place or whatever, you could probably just as easily use some copper wire instead.
