Personally I wouldn't worry about nailing precision with a 9-week-old puppy. At this point my focus would be more on developing foundational behaviors/fluencies, attention/engagement, and tricks.
Is this the first dog you've trained for competition? If so, I'd definitely go for foundations and tricks rather than formal obedience behaviors.
Pongu was/is my first dog, and what I found was that the trick training made me a much better trainer and did a lot to develop his love of work (not to mention his rear-end awareness and coordination), so that paid off hugely in the long run, but my early efforts at installing formal competition behaviors mostly sucked because I didn't know what I was doing when I taught those. I had to go back and re-teach a lot of that stuff from the beginning once I knew what they were actually supposed to look like. It ended up being a lot of wasted effort and confusion for my dog.
