I think this might be what you're looking for, there are two ROM routines that can help: $9491 : check comma $9D84 : get one byte to x register.
This little example will let you set a TED register:
A 012C JSR $9491 JSR $9D84 STX $D0 JSR $9491 JSR $9D84 TXA LDX $D0 STA $FF00,X RTS
To use, you can do something like this:
SYS300,DEC("15"),DEC("32") : REM $32 to $FF15, set background color to red SYS300,DEC("11"),DEC("38") : REM $38 to $FF11, turn up the volume and turn on both channels
