I have also taken the dust cover off the shifters and used WD-40 and then Tri-flow after things have dried out and had good success. But if the shifter is worn out, you need to replace it.
Is it 8 speed?

yes it is an 8 speed.
My concern with taking the cables out is that the group doesn't have a cable tension adjustment on the shifter; it is just on the derailer but that one is broken. Hence the goal of replacing the derailer and shifter at the same time.
I will however take the dust cover off and try the WD-40. I don't have tri-lock, will any fine spray lubricant work? I have a graphite lubricant that I have used for motorcycle cables in the past.
