Hi cestfemme!
Gorgeous dress :) i agree witht he other 2 - the train doesn't look too long, so you may be able to deal with it. If you do end up wanting to bustle it higher, I would definitely do a french bustle, as your dress is already designed that
way.
After the ceremony, are you planning to walk around a lot? If not, then I'd do w/o it...maybe try walking around during your fittings and see if it drags too much.
