when to start trapping, sectoring, open hand kali, grappling

I am wondering if you guys who train others how far into training do you start incoperate trapping, some open hand kali, sectoring which is simutanous parry strike, and some grappling skills. The way i start off is footwork then basic punches, kicks, covers bobs and weaves, just being able to try and read the different line that a strike can from having there body be able to react in the moment. Then after that i would start trapping and some of the other tools. Do you think that is a good way to start and then lead to tools. I use focus gloves alot for timing and eye cordination then use the heavy bag to build some power. Anyway let me know what you guys think. Thanks
