In my opinion it is absolutely okay to ask such questions on MO. Your idea of bundling together related smallish questions is probably a good one.
By the way, "easy" is certainly a subjective term, but I have yet to hear it used to describe any of the work of Beilinson and/or Drinfeld. I for one look forward to the possibility of learning something about this topic by sheer osmosis.
The only problem with questions like this is that they tend to be very technical and often will not receive any answers for a long time, but that's only really a problem for you, not the site itself, so feel free to do it =).
