That probably won't do much, since the body doesn't work acutely like that. Just keep training legs hard and train them 1-2x a week. 

Squat daily for 4-6 weeks to get them some extra volume then switch to another program that hits legs 2x a week. See the squat daily program here: https://content.tigerfitness.com/squat-every-day-total-body-program/

Of course you can, it's just protein and protein is also added to...baby formula!

There is no timeline for "too fat" and "lean enough". Bulk slowly, gaining 1-2lbs a MONTH and stay UNDER 15% body fat and cut until you are happy with how lean you are.

1) Taking it with every meal won't hurt, but full dosing is two meals a day. Around training with carbs is optimal.
