Question bathroom remodel -tile/floor questions

Helping a buddy remodel his bathroom, and I have a few questions.

1. Removing counter/backsplash (1 piece) from tiled wall? Easiest way to avoid damaging the tile?

2. Subfloor - Previous owner layed linoleum on top of plywood subfloor, no extra layer and hardly any glue to deal with.The subfloor shows minor signs of water damage and seems brittle. Should we lay another thin layer of ply to make the floor more stable? He was planning on just using 1/4 backerboard. Is that enough?

3. What size of trowl to lay 6x6 floor tiles?

1.) Break the bond of grout or caulk between the bottom row of tile and the top of the counter. Then try rocking it side to side. Dont lift too much as that will put pressure, by rubbing, on the tiles and they could chip or crack.
2.) Remove the vinyl. What thickness is the remaining plywood? If 1/4" luan is there that must be removed also before putting new underlayment down. 1/4" cement board ultimately will be fine but you may need another layer of plywood, dependent on answer to above question, to give subfloor appropriate strength to carry tile without cracking.
3.) 1/4" square notch trowel. Use modified thinset.

No luan, and I should have clarified we're removing the vinyl. One layer of 3/4 ply with some minor water damage. I suggested another layer of 1/4 ply. Sound good? Thanks for the advice.

Dont use the 1/4" plywood, go with 3/8" BC grade at a minimum. Tile Council of America guidelines want at least 1 & 1/8" of plywood down as subfloor. Then put the 1/4" cement board down, embed it in thinset and nail off with galvanized roofing nails, preferably hot dipped if you can find them. After all that you can start to tile.
