When you get the book, you will see that she does not advocate a complete conversion to combined knitting. Instead, she suggests using it in certain circumstances -- such as ribbing or flat stockinette -- where it's practical and feasible, and gives a better result than continental or english. To be honest, I found the book a bit disappointing, and actually think grumperina's chart is more helpful in spelling out how to do specific things such as increases and decreases. (Even that has it's limits, though; you can search for some old threads on the topic.)
For those times when you don't know how to do something in combined, I think that the simplest solution is to just re-position the stitch as necessary (so it's mounted "correctly") and then proceed as you would if you were using continental.
