Tomorrow I’m supposed to go to my beloved Vinyasa class. IF I can get up at 4AM tomorrow I plan to do W1D2 of Strength and do my Vinyasa at 745 that evening. Am I okay with not over training? How about for nutrition?

You are great to do both. If you feel like you are not recovering, I would recommend splitting them up. If you want to add an extra serving of starch into your last meal for energy, go for it because you will have just finished working out.
