Ready to wire up "Thor". Grounding schemes. Any?

[pd3]

Ok, the CB and enclosure are complete, everything is mounted, and its time to wire up the darn thing.   I built it according to the pictures on "Runnoffgrove" using the  pad per hole type board.  Its almost exactly the same, difference being that I ordered Silver mica caps for the picoFarad range caps.  Kinda ran out of room in one place and soldered one of the caps underneath the board.   I am wondering if any of you have opinions, preferences, indifferences regarding wiring, in particular, the grounding.   Some of the questions popping up in my little head are:
1.  Should any grounds stay separate? Input from output?  Chassis from signal?   Doesnt matter?  Can't have them separate? 
2.  Is there a minimum lenght of signal carrying wire you would allow before shielding?  Some of my distances from board to switches/pots are only 1" to 1.5". 
3.  Anybody find an improvement if star grounding some of the returns?
I found it surprising when my amp tech (well known guy in Boston, musician that makes many of his own fuzz and dist pedals) stated in response to my questions that it's really nothing to sweat much about.  Just dont let input and output wiring get too close.  He said that "the enclosure is grounded anyways and everything is mounted to it.  You should be able to let all the grounds meet each other without a problem. If there is a noise problem, then you can experiment a bit with ground runs."  Well, thats what he said.   I've always automatically star grounded the hand ful of pedals I've made just to play it safe.   I'd really like to hear your  input on this topic. Particularly on Thor like pedals .   If there is something someone knows that can help to improve potential noise, I'm listening.  This pedal is to be an important part of my sonic pallet for my second job. Would like to get it right I say!

Thank all for your time!

Well, I guess that makes all of this pretty straight forward. 

Thanks!

in my opinion, grounding IS a thing to worry about. i´ve tried different ways of wiring in my ocd clone, and there were many  differences in noise level and switching pop level. i couldnt eliminate he switching pop completely though. its not the LED, its something else....
