The 10 gallon mash tun is fine for normal beers unless your normal is over 1.060 which mine usually is. I use a 5 gallon cooler for 3.5 gallon batches but if I need to do anything "imperial" I need to use the 10 gallon cooler for just a 3.5 gallon batch. Of course my efficiency is only 60% due to no-sparge brewing. Even before switching over to a countertop Brutus system I nearly filled my 10 gallon cooler on every 5 gal batch.
So here you can go 60qt coleman or 20 gallon pot for direct fire if you tend to always do bigger beers.
For your kettle, if you want to go cheap get a keg and convert it. If you want to go bling, I would get a 20 gallon pot. Everyone's opinion is different but I like to have twice as much kettle as my batch size so I don't have to be so "on the ball" watching out for boil overs.
Build that CFC first.
Ensure you have proper fementation temp control before spending money on anything else. It's better to have 5 gallons of great beer than 10 gallons of so-so beer.
Take all the above suggestions with this in mind. I "upgraded" my brewery by down sizing from 5 gallons to 3.5 gallons all electric so I may just not have a fricken clue as to what you need.
