Use sanded grout if the joint is bigger than 1/8", use unsanded for 1/8" and smaller.

The additive can be used if the directions on the bag of grout say it can, some grouts can only be mixed with water, putting the additive in changes the chemical balance. The additive is good because it keeps the color more uniform and stays closer to the color they advertise it to be. Be careful because it dries fast so dont get ahead of yourself when spreading the grout or it will be harder to clean up.

Tape the seams of the cement board with mesh tape. You can do this as you set the tile. Cover the tape with modified thinset so it gets pushed down through the tape and into the 1/8" gap you will leave between boards.

Yes, you can use the cheap, unmodified stuff under the cement board, it is there to fill gaps and voids, not to bond, the nails/screws take care of that.

Self Leveling Cement (SLC) is used after the cement board goes down, if you have a dip in the floor that you want to fix before the tile goes in. When mixed with water it pours out on the floor like pancake batter on the griddle, goes down smooth and flat. Why do you ask, do you think you need it? There is more to know about using it.

not sure what I need really- just trying to find out all that I can- do my research before Friday-- we had a tile layer lined up but did not work out, next guy never returns phone calls- both are too busy so now we are doing it ourselves and have no real experience in tile. I think the floor is ok- has subfloor and 3/4 underlayment- house is only 15 years old but did not know.was not real sure how you know. also trying to figure out best way to cut door frames

Beg, borrow, steal, or buy a jamb saw for about $12. Determine where you want to cut, and lay a correct thickness board in the doorway (to guide and keep the saw level) and cut off the jamb.
