I'd use BM45 for the yeast, this has produced a wine almost identical to a commercial Amarone, put it through Malolactic fermentation, use Bacchus or VP41, get some tannins, tannin riche works real well with this wine.
If you don't have an oak barrel, I'd add 2 oz of chips (medium toast, french) to the fermenting bucket, the yeast metabolizes it resulting much like an oak barrel, I'd get a few oak infusion spirals, again, medium toast french, you will be very happy with the results.
I have made a few batches from juice buckets that are absolutely amazing, I cannot wait to get more this fall, this time, I'll buy a lug of fresh grapes and ferment it on 9 lbs of fresh crushed grapes, it makes an amazing wine.
