You're not going to get an accurate maintenance caloric intake from taking an online survey, you'll have to work it out by monitoring your weight over time. I'd say if you're trying to put on mass then you stay roughly 100/150 calories above your threshold, I would assume that if you want to keep gaining then you would keep on eating during your rest days, there is plenty of guidance as to what value of macro's you should be taking in to gain mass. Usual rule of thumb would be 1.1-1.2g of protein per lb of weight that you are looking to achieve in the end, so in your position around 190g of protein to gain muscle and then work out the rest of your macros.
Edit: If you are actually serious about getting bigger 2 days a week is not gonna cut it.
