I am not an Apfelwein expert, but I would say the answers to all of the above are YES.
My first batch was made with 50/50 Dextrose and Brown Sugar and turned out great. My second batch (in the carboy for 8 weeks and almost ready for bottling) was done with about 60/40 Brown Sugar/Dextrose.
I saw a Cider yeast comparison here:

and EC-1118 got a pretty high rating for taste. I assume what they call Lalvin #1118 is indeed EC-1118. I have used it for Meads, and it will take you to DRYNESS and BEYOND for much higher OG than you will find with Apfelwein!
Interestingly,, the Ed Wort preferred Red Star Montrachet got pretty poor results in this experiment.. As usual, mileage may vary.
Only downside I can see to a bucket is not being able to observe the clearing process.
..BTW, my Local Brewshops are not all that local, and I order almost all of my supplies online.
