> How can I clear the screen with grayscale activated?
  
call CLEARLCD       ; clear the first page.

clear_page2:            ; clear the second page
 	ld 		hl,(PAGE2ADDR)
 	ld 		bc,1024
 	call 	OTH_CLEAR
 	ret

You might want to do this to save bytes if you clear it a lot:

CLEARLCD_GRAY:                         ;Usage: call &CLEARLCD_GRAY
 	ld 		hl,(PAGE2ADDR)
 	ld 		bc,1024
 	call 	OTH_CLEAR
      jp          &CLEARLCD
