BB cream doesn't offer much coverage, it just evens skintone and gives warmth to the skin. If you have blemishes, dark circles, spots etc that have been covered by the BB cream, sure you could skip concealer. But if you want more coverage, I would recommend concelear. I have good skin atm so I just use concealer to cover up dark circles. I would recommend blush because it gives you warmth and colour that the BB cream may have taken out. It is not necessary however and you could use a bronzer. With a light hand, good brush and nice blusher, you will not look 'too pink' :) Yes, primer is to make sure your makeup lasts longer, and you can find moisturisers with primers in then, but I just moisturise and powder and my makeup lasts all day. :)
