Sounds like a good set of nutritional guidelines. The only thing that I'd be wary of is adequate nutrition for recovery from your rugby sessions and matches. That's going to be a take it as it comes process if you feel like death after a week and your sleep and everything else is good then you might have to up your food a bit.
With that many practices I'd say the only thing else to to look at what you do on the 2 days you have availible to train. What do you currently do those 2 days?
Will you be playing rugby up until Christmas?
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
