Insufficient information. The size is not what determines DR.

I suggest that you advise your boss to get someone who is familiar with implementing HA/DR in to advise, design, implement and train.

I must repeat Gail's advice, get an expert in to lead the effort. Only in the simplest of such situations would I even consider offering any advice via the forum, there are simply too many variants in the equation.

And to re-enforce, I would be hesitant to take on a DR project for a critical DB as it's not something I'm incredibly familiar with. It's not something to be approached lightly.

The best piece of advice, go and get someone who knows what they're doing. You go past about 2-3tb and the rules change pretty radically. It's not something you can approach lightly.

In general, you need to have a great understanding of the business first. Then you can worry about the technical aspects of setting up a DR plan for them.

But there's no way to even make suggestions based on what you've told us. As for tempdb, I'd suggest having a read through on several articles over at sqlskills.com. They've got some very good information on how to configure it correctly.
