How do I guesstimate how large a cooler I will need for full boil 5 gallon batches? Is there a magic formula for X qt cooler per gallon wort size?

It depends on what your efficiency is, what is the highest OG brew you want to make, how thick you mash, whether you fly sparge or batch sparge, and probably a whole bunch of other factors.

See http://www.rackers.org/calcs.shtml (can I mash it) for a great calculator, and err on the side of bigger is better.

Min 20 qt., max 48 to 52 qt. for 5 gallon batches IMO.

Thanks for the link. That is what I was looking for.
