You need to decide if you want to add some weight (muscle) or lose some. I would be suggesting adding weight as it's likely that even when you lose that last bit of belly fat, muscle could be lacking.
At you're weight, I'd estimate maintenance around 2100cals but that depends on how active you are in everday life.
2500 cals would be a good start if you do want to gain some weight I'd say. As always, access and readjust where necessary. I'd agree that you do have adequate protein there and most likely adequate fats too so looking pretty good in all.
Just a note: if you're happy to eat the same thing every day then go ahead and do that but it's not necessary to. Same thing re no. of meals. If you want that many, go ahead. What matters most is that you are getting adequate macro/micro nutrients and total cals to gain weight. You're body doesn't see food names, just macros/micros.
Hope that helps
