Well for Paper choice I prefer buying the full sheets of Light blue or blue Canson Mi-Teintes, I prefer to work with the textured side vs the smooth for portraits..I have no clue why! LOL I just do
I am about to embark on some wildlife pics and I am in love with the Sennelier Textured board, I plan on using the tan color.
I use Acid free matting, with the cut beveled inward to help reduce dust issues.
When Ever I finish a pic, I place it on foam board with mounting tabs and cover for storage.
I use foam board as a backing...and it may change depending on what and where the pic is going. For example, if it was to be a show piece I would let the Professional Framer (lol) do it!!
Hope that helps!!
