For general computer questions, you can go to Super User. With luck, someone there has been using the same software that you have, and can answer any questions you have.
For questions specific to construction work, there is a site proposal on Area 51. The site isn't there yet, but is far in the commitment phase.
No, I don't think so.
But you can propose such a site on Area51. It might be a bit too specific to find enough followers/committers though.
