It sounds like you have covered all the basics...any additional emphasis areas would probably depend the on the examiners past history...presumably you know something about him?
You said you're doing a 141 program...will your CFI checkride be conducted by an in-house 141 examiner (as opposed to a Fed or DPE)? Few schools have this privilege with CFI rides, but if yours does, then you should take the 141 in-house ride because you cannot "fail" it...the worst that can happen is that it is incomplete, and you re-do the stuff that wasn't right, ie no pink slip. Also, it's a more relaxed environment with an in-house examiner.
If you have to fly with a Fed or DPE anyway, you might want to bail on the 141 course and take the ride immediately. Since there are no time requirements for a CFI checkride if you feel ready and can get the sign-off you can just take the checkride part 61, rather than finishing the 141 course...I had students do this routinely when I was a 141 instructor. Just a thought.
