Hey Alco,
In answer to your questions, the short answer is yes to all of the above.
If you ask to see their equipment, it shows your interested.
Call volume is important, that's why you"re there.
Community outreach is a good topic, but perhaps bring that up at your next interview. ( if there is one ) At this stage, your trying to sell yourself.
A pad and pen is not inappropriate. Keep it with you as reference, but try and know the questions you want to ask, it shows confidence.
Good luck!
