You can easily lift the vehicle high enough to clear a drill with bit. You don't need to use a drill to extract the screw with the easy-out; I would actually recommend against it. Once you drill the bolt, place the screw extractor into it and give it a very gentle tap with a hammer to get it started in there, then turn it out by hand. I use a t-handle tap wrench with screw extractors, but you could use a standard wrench of some sort as well.
If you cannot get it and are willing to remove the oil-pan, clean the block on both sides near the hole with the broken bolt, then heat the block with a torch. This will make it much easier to get the broken screw out.
If that doesn't work, purchase a helicoil (or equiv.) kit and use that.
I would not use a grade 8 bolt (class 10.9) for fear that it would be stronger that the block. Stick with a class 8.8 in this case. It's generally better to break a bolt than to strip the threads out of a bolt hole, IMO.
