Acrylic Tub Lip/Tile Base Surround Question

Remodeling a lower level bathroom
Wondering the best way to do the lower row of tiles that meet up with the tub. The tub is acrylic and has the usual 1"tall lip around the top of the tub that is about 1/4" thick.

What I was thinking of doing is countersinking that lip into the durarock and running the tile down below that 1" to the tub, then after grouting - caulk it where meets the tub. Bad idea? Other ideas?

For countersinking that lip I was thinking of scoring and scraping away enough durarock to get it to countersink

The tub will be set in Mortar and I dont have the instruction here in front of me but do you pre drill and screw the tub to the framing?

Thanks for your time - I searched for questions like this on here but didnt find anything too thorough.

The tile board can just go to the top of the tub lip and the tile is set in a thin set the rest of the way leaving a small gap between the top of the tub and the tile for silicone caulking.
That's one way, the way I do it is shim out the studs with lattis so I can set the tile board about 1/2" above the tub. Less chance of a leak.
Use galvinized roofing nails to attach the tub to the studs once it's been leveled.
Screws stick out far.
