I second expat and jjj75's advice. The insurance is likely global coverage, and you can bring your kids over on visitor visas while you wait for your and their RPs.
Ask you HR on how long this would take, but I wouldn't think more than a month.
Personally, if it's less than a month, my advice is for you to come and get settled on your own and then have your family join you shortly afterwards. Put them on one of the direct flights from the U.S. on Qatar Airways so that your wife doesn't have to work about changing planes in a foreign country. Also consider having a grandparent or other relative travel with them. It will help with the travel and when getting settled here, because you'll be a work and your wife will be exhausted.
