You won't get any off flavors from the krausen unless you leave the beer in primary for 2 or 3 months. The "hangover contributing resins" you are talking about are the fusel alcohols that result from fermenting at too high a temperature, not from anything in the krausen. The krausen contains a lot of yeast that will help in getting your beer down to your target final gravity, so you don't want to skim it off.
Blow off tubes are needed now and then even with the 6.5 gallon fermenter, especially with 1.065+ beers and many wheat beers.
