Don't drop the creatine. It will help you maintain your strength levels.
As for cardio, I wouldn't do it for fat loss. If you want the better cardiovascular health, go for it. Do what you enjoy for a bit after your workout whether it's biking, rowing, whatever (I'm partial to rowing). I also like to toss 5-6 minutes in before I lift to bring my core temp up a bit before I even stretch, especially in the winter when it's freezing out.
I don't know your current condition but if I recall correctly, HIIT cardio has shown to have a greater effect on VO2 max compared to SS cardio. It really depends on the kind of adaptation you're looking for.
