I think the 840cfm will work perfectly, go for it!

Yes...I did, but I've not sat and looked over this with my engineering hat as I should have...I would pull fresh air in, BUT...you're right in that it would be cold air during Winter. If you have air that is able to come into the room from other areas, under door(s), etc...in which I am sure you do, then you may not need the outside to inside air fan. Thus, not needing a duct heater. If you do pull in outside air, just to have it as an option (it really helps "flush" out the room quicker...then I'd recommend the duct heater.

I've seen photos of the exhaust and fresh air intake side by side on the outside of the house in others cigar room. Doesn't that defeat the purpose of a fresh air intake? Wouldn't the intake pull the cigar smoke from the exhaust right back in? (photo below)
You are correct and I would never recommend the two be close! If you can put on different sides of the room (if two exterior walls), then please do...or at the least, try and separate as much as possible. But, this will only apply if you are bringing in outside air.

You are fine, ask away. However, it looks like you may have already ordered stuff and if so, I am sorry for my delay in getting back to you. I don't frequent this forum anymore and I only log in to see if you've needed anything else! I just hope I was able to help you in some way...and not confuse you!
