I don't use star grounds in any pedals. So long as you avoid a loop you should be OK. In recent stripboard builds I have followed this scheme from Tag Board Effects. The ground follows one neat line, no loop. You can sort of see it here:
Compared to the diagram, I don't wire the LED directly to the footswitch. I make a tiny board from stripboard and solder the CLR, LED, and wires to that. It's a bit hard to see in the photo since it's over the main board. I like this approach since it lets me position the LED anywhere in the enclosure.
