I'm afraid I don't have any easy answers for you; what you seek is the equivalent of learning to run before you walk. I don't like to discourage players from experimenting and trying new approaches, but the chocobuck limitation you've placed makes it exceedingly difficult.
What you need to do, is pack as many overall "points" into your chocobo by any means possible before day 64. Use Kamp Kweh and appropriate foods to get as many extra points as you can. And since physical training tends to decrease mental training, and vice versa, you'll want to drive one pair of stats (generally, physical) up fast while letting the other hang at zero (thus causing the minus side of the training to have no effect on your overall point balance).
Then as you near maximum for one pair of stats, switch and just suck up the negative effect, since you still get a slight overall boos in point total. It is a matter of debate which training regimes are best -- while models of points gained/lost exist, their accuracy is debatable. Personally, I focus on Carrying Packages / Exhibiting to the Public, but I have no evidence to suggest if this is better or worse than other combinations of training.
Once you hit Day 64, whatever point deficiency you have must be made up with tokens. Looking at the chocobos I've raised, I would expect to spend some 20-30 tokens at least to reach cap at the end, assuming a well-optimized care plan.
