There should be no problem placing a chock in front of the rear duals--it is amazing what a small bump will do to hold a vehicle back if there is no push to get it started.
As far as backing in and blocking traffic--wouldn't you have to cause the same blocking when you backed out if you head in first?
Have seen several Cs with the front elevated with the jacks (with/without blocks under them) and then the front wheels lowered onto other blocks to take some of the weight off the jacks.
Never having owned one of them, maybe I am off-base on the ideas...
