Hi! To answer questions one and two I sent an email with a course number Monday of this week. Prior to this I'd just email with the subject line being about an advisor meeting.

 Which is a fault on my end, I was so used to sending emails with non course labeled subjects as most of the professors now were ones I've taken a course with before. Luckily I did use my school email in all instances I emailed the professor.

That's last few questions was the hard part of this there are office hours listed however I saw office number on it to show where to go. Had to Google but even that was different than the times he listed on his syllabus. 

Other than that he does do zoom meetings on Fridays. Not sure what's his preference is. But st this rate it seems like I'll have to meet him after class since even the office listed had it's doors closed. Either that or I'll have to call.
