Sold my car/NEED you advice

[Philly X5]

Ok,
I sold my 330ci and will be getting my X5 next week

Here is the question:

Sold it on eBay to some guy from NJ with good/solid feedback
He is coming this Saturday to pick it up and finalize all the paperwork.

This is the first car I sold so sorry for all these questions.

1. He wants a copy of the Title to be emailed to him - should I do that?
2. He wants to know my address or place where we can get together - should I give my address?
3. Wants to pay with check - I requested Certified Bank Check
4. Do we need to go to the DMV after I get a check or can I just sign a Title and give it to him?

Please someone let me know. Thanks.
