I have done some of this in my place before. I am not sure what the pros would do though.
1) Mortar, add Bondcrete to the mortar mixture - this is sort of like glue for cement. It should ensure that there is a good bond between the new cement and the old. You will want to ensure that the old cement is clean (ie no alae/mould etc buildup).
The new tile can then be put on that as long as it is not too deep. Otherwise a product like resiflex (like a rubberised tile glue) to stock the tile on.
2)Not sure how to really clean them up - I just carefully scraped the old out (yeah, bugger of a job). Don't use anything like a wire brush as this will scratch the tile and then encourage mould growth.
3) Again, not sure what the correct method is, but I grouted the whole lot. THEN siliconed the complete floor corner/edge. Trick i was taught was to have a cup of water that you dip your finger into to smooth the silicone. That way the silicone does not pick up and you get a nice smooth edge. Also, don't use the cheap silicone from the $2 shop.
4)See (3) for silicone. Apply the grout and using a damp sponge, wipe over it all. It does not matter that a fine dusting of grout ends up on the tiles. Once all is dry, wipe over with a wet sponge and this should wash off.
5)Not sure of this - movement of the tiles etc (ie preparation of the shower surface before laying the tiles) will play a big part. If the floor moves ie laid on timber without a fibreboard base, the tiles will move and cause the grout to crack up. Not much you can do about that now though, except make sure that the piers/beams under the bathroom are packed well (ie between pier and beam is tight and not 'bouncing').
That is my home handyman experience anyway.
