You don't need an airlock if you're cold crashing. Fermentation is done at that point. Just seal your fermenter.

I'm not sure what you mean by "suck back," but if you're simply putting your better bottle into a low temperature space, then oxidation wouldn't be a worry. If you're transferring into a secondary better bottle, then it is a very minor concern that I wouldn't worry about. Try to keep your racking hose below the liquid level to minimize any splashing.

So seal it up with a bung and crash, will I suck in o2 when I open it to transfer? These are really big ipas so I want to crash to drop out the massive amts of dry hops before moving to my kegs. Thanks

You could put a bung in it, but it might be difficult to remove. I usually just use foil and a rubber band. No worries about oxidation from opening it.
