Has anyone used Tableau integrated with NetSuite data?

Yes. Do you need help with this?

I'd certainly be interested in any general pointers/advice you had. We're just starting to look at this ourselves. Did you go with a 3rd party integration service?

I can have a number of consultants who specify in this area. Some will go with 3rd integration service some won’t, depends on their style and what is best recommended for your company after assessing your data
