Hello 
For a general guide and progress map, I’ll point you in this direction:
For how to divide your time: it’s recommended that srs take up no more than 25% of your study time. If I were in your shoes, with one hour a day, I would do 30 minutes of grammar study, 15 minutes of Wanikani, and split the remaining 15 minutes between reading and listening. The reason there’s so little time for reading and listening is because without grammar knowledge, you won’t understand much. This is why it’s important to start grammar asap! Then as your grammar knowledge increases, you can start shifting time from grammar study to reading and listening.
