Yes, you need to be at least one st in from the edge to do the lifted sts. (As I mentioned in your previous thread I don't like doing them on the edge for seaming purposes.) BTW, whether you knit cont or Eng isn't a factor.
The L/R, F/B can be confusing. For right slant, make sure the lifted st is twisted (back/left leg to the front)...work thru the front. For left slanting, st should sit the same as your other sts but is worked thru the back.
