crafting stalls

i have just got goldsmithing crafting stall but dont have the sign board or fools gold or the gemscope however i have got the mega mooglification as major light arua, so does that give me +5 in the skill now or do i need the other pieces to get the 5, i kinda wish that with extras like this they could put a +2 for gear and +5 for stall next to your craft so you can actually see it. so do i need the other pieces or not?

noones quite positive one way or the other. And the devs haven't said either'
